A 1.5 inch tall preying mantis will sometimes hold its ground and attempt to fight a person who is 6 feet tall. If a person who is 6 feet tall is engaged in a battle with an animal that was proportionally as tall as the person is to the preying mantis, how tall would the animal be?

In terms of inches, 6 feet = 72 inches
Set up a proportion of height of smaller creature to larger creature where h is the heigh of the animal
1.5/72 = 72/h

Using our proportion calculator, we get:
h = 3456 inches

In terms of feet, we have 3456 inches = 288 feet
