A cereal box has dimensions of 12" x 3" x 18". How many square inches of cardboard are used in its construction?
A cereal box is a rectangular solid. The volume formula is V = lwh.
Substituting these values of the cereal box in, we have:
V = 12(3)(18)
V = [B]648 cubic inches[/B]

A circular balloon is inflated with air flowing at a rate of 10cm3/s. How fast is the radius of the ballon increasing when the radius is 2cm?
[U]The volume (V) of the balloon with radius (r) is:[/U]
V = 4/3?r^3
[U]Differentiating with respect to t, we get:[/U]
dV/dt = 4/3? * 3r^2 * dr/dt
dV/dt = 4?r^2 * dr/dt
The rate of change of the volume is:
dV/dt = 10cm^3s^?1
[U]So, we find dr/dt:[/U]
dr/dt = 1/4?r^2 * dV/dt
dr/dt = 10/4?r^2
dr/dt = 5/2?r^2
Therefore, dr/dt(2cm) is:
dr/dt(2cm) = 5/2?(2)^2
dr/dt(2cm) = 5/2?4
dr/dt(2cm) = [B]5?/8[/B]

A cube has an edge that is x cm long. What is the capacity of C(x)?

A cube has an edge that is x cm long. What is the capacity of C(x)?

A cubical storage box has edges that are 2 feet 4 inches long. What is the volume of the storage box

A cubical storage box has edges that are 2 feet 4 inches long. What is the volume of the storage box?
Since 1 foot = 12 inches, we have:
2 feet 4 inches = 2(12) + 4
2 feet 4 inches = 24 + 4
2 feet 4 inches = 28 inches
We type [URL='https://www.mathcelebrity.com/cube.php?num=28&pl=Side&type=side&show_All=1']cube side = 28[/URL] into our search engine to get:
V = [B]21952 cubic inches[/B]

A lead pipe 20 ft long is 3/8 inch thick and has an inner diameter of 3 inches. Find the volume of l

A lead pipe 20 ft long is 3/8 inch thick and has an inner diameter of 3 inches. Find the volume of lead in it.
A lead pipe is a cylinder. We want the volume of a cylinder.
Convert 20ft to inches:
20ft = 12(20) = 240 inches
Find the inner radius:
1/2 * inner diameter
1/2 * 3 = 3/2
Now add the thickness for the total radius
3/2 + 3/8 = 12/8 + 3/8 = 15/8
Find volume of the lead where volume = pi r^2 h
Lead vol (V) = Overall volume - inner volume
Lead Vol = pi(15/8)^2(240) - pi(3/2)^2(240)
Lead Vol = 240pi(225/64 - 9/4)
9/4 = 144/64
Lead Vol = 240pi(225/64 - 144/64)
Lead Vol = 240pi(81/64)
[B]Lead Vol = 303.75pi[/B]

A mug has 3 inch diameter and is 3.5 inches tall how much water can it hold

A mug has 3 inch diameter and is 3.5 inches tall how much water can it hold
A mug is a cylinder. If the diameter is 3, then the radius is 3/2 = 1.5.
Using our cylinder volume calculator, we get:
[B]V = 7.875pi or 24.74 cubic inches[/B]

A rectangular fish tank has a base that is 8 inches by 7 inches. How much water will it take to a de

A rectangular fish tank has a base that is 8 inches by 7 inches. How much water will it take to a depth of 5 inches
The volume (V) or a rectangular solid is:
V = lwh
Using l = 8, w = 7, and h = 5, we have:
V = 8(7)(5)
V = [B]280 cubic inches[/B]

A rectangular prism has a width of x feet, a length of y feet, and a height of h feet. Express its v

A rectangular prism has a width of [I]x[/I] feet, a length of [I]y[/I] feet, and a height of [I]h[/I] feet. Express its volume in square inches.
V = width * length * height
V = xyh
12 inches to a foot, so:
In cubic feet, we have 12 * 12 * 12 = 1728 cubic inches
V [B]= 1728xyh[/B]

A spacecraft with a volume of 800 cubic feet is leaking air at a rate of .4 cubic feet every [I]n[/I] minutes. How many minutes until the spacecraft has no air?
800 cubic feet / .4 cubic feet every n minutes = 2000 (n minute parts)
Total time = [B]2000n[/B]

A spherical water tank holds 11,500ft^3 of water. What is the diameter?

A spherical water tank holds 11,500ft^3 of water. What is the diameter?
The tank holding amount is volume. And the volume of a sphere is:
V = (4pir^3)/3
We know that radius is 1/2 of diameter:
r =d/2
So we rewrite our volume function:
V = 4/3(pi(d/2)^3)
We're given V = 11,500 so we have:
4/3(pi(d/2)^3) = 11500
Multiply each side by 3/4
4/3(3/4)(pi(d/2)^3) = 11,500*3/4
Simplify:
pi(d/2)^3 = 8625
Since pi = 3.1415926359, we divide each side by pi:
(d/2)^3 = 8625/3.1415926359
(d/2)^3 = 2745.42
Take the cube root of each side:
d/2 = 14.0224
Multiply through by 2:
[B]d = 28.005[/B]

Anna is collecting boxes of cereal to deliver in a food bank. The volume of each cereal box is 324 c

Anna is collecting boxes of cereal to deliver in a food bank. The volume of each cereal box is 324 cubic inches. The picture shows the cereal boxes she has collected so far. A large delivery box holds three times as many boxes as Anna collected.
About what is the volume of the delivery box?
The picture has 12 cereal boxes. Since the delivery box holds three times as many cereal boxes as Anna collected, the delivery box holds 12 * 3 = 36 cereal boxes.
With each cereal box having a volume of 324 cubic inches, we have the total volume as:
V = 324 cubic inches * 36 cereal boxes
V = [B]11,664 cubic inches[/B]

if hose a can fill up a swimming pool in 6 hours, hose b in 3 hours, hose c in 2 hours, how long will it take to fill up the pool using all 3 hoses?
Let V be the pool's Volume. Each hour, the hoses fill up this much of the pool:
[LIST]
[*]Hose A, V/6 of the pool
[*]Hose B, V/3 of the pool
[*]Hose C, V/2 of the pool
[/LIST]
Effective fill rate is:
V/6 + V/3 + V/2
6V/36 + 12V/36 + 18V/36
36V/36 which is volume units per hour
Let t = units / rate
t = 1 hour, so we have:
t = units / rate
t = V (volume units) / V (volume units / hour)
t = [B]1 hour[/B]

A box in the shape of a rectangular prism is used in a movie scene. The base of the box measures 6 feet by 5 feet. The box has a volume of 195 cubic feet. The director hires an actor who is 6 feet 4 inches tall. Can the actor stand up straight in the box?
Also I do need to show my work so please write down the work to solve this. Thanks!

Math Problem Solving (Help Please)

Volume of rectangular prism is:
V = lwh
Plugging in the numbers you gave:
195 = (6)(5)h

Divide each side by 30
h = 6.5
6.5 feet is 6 feet, 6 inches. This is 2 inches more than your actor, so [B]yes[/B], he will fit in the box standing up.

Three tennis balls each have a radius of 2 inches. They are put into a 12 inch high cylinder with a 4 inch diameter. What is the volume of the space remaining in the cylinder?
Volume of each ball is 4/3 ?r^3

True or False
(a) The normal distribution curve is always symmetric to its mean.
(b) If the variance from a data set is zero, then all the observations in this data set are identical.
(c) P(A AND A^{c})=1, where A^{c} is the complement of A.
(d) In a hypothesis testing, if the p-value is less than the significance level ?, we do not have sufficient evidence to reject the null hypothesis.
(e) The volume of milk in a jug of milk is 128 oz. The value 128 is from a discrete data set.
[B](a) True, it's a bell curve symmetric about the mean
(b) True, variance measures how far a set of numbers is spread out. A variance of zero indicates that all the values are identical
(c) True. P(A) is the probability of an event and P(Ac) is the complement of the event, or any event that is not A. So either A happens or it does not. It covers all possible events in a sample space.
(d) False, we have sufficient evidence to reject H0.
(e) False. Volume can be a decimal or fractional. There are multiple values between 127 and 128. So it's continuous.[/B]
