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.
