Question

Ian buys a rectangular water cooler that has a volume of 4 1/16 cubic feet. The water cooler is 1 1/4 feet long and 1 feet wide.

Complete the following sentence.

The water cooler is
feet high.

Answer 1

To find the height of the water cooler, you will use the formula for finding the volume of a rectangular prism and solve for the missing height.

V = lwh
4 1/16 = 1 1/4 x 1 x h; simplify the right
4 1/16 = 1 1/4 h; divide both sides by 1 1/4
1 1/4 1 1/4
h = 3 1/4 feet

The height of the water cooler is 3 1/4 feet.
