How many square feet of material do you need to cover a cube with length 57 width 44.5 and depth 50?
Assume the measurements are in feet. Then the area of two opposite sides (say front and back) = 2 x 57 x 44.5 = 5073 sq ft The area of two other opposite sides (say top and bottom) = 2 x 57 x 50 = 5700 sq ft The area of the remaining sides (left and right) = 2 x 44.5 x 50 = 4450 Total area of material required = 5073 + 5700 + 4450 = 15223 sq ft. NOTE : If the dimensions are in inches then the total area = 15223 ÷ 144 = 105.72 sq ft.

Each wall in Zach's bedroom is 11 feet long and 8 feet high. Zach paints 3 walls of his bedroom orange. How many square feet does Zach paint orange?
To find the total square footage Zach paints orange, we first calculate the area of one wall: 11 feet (length) x 8 feet (height) = 88 square feet. Since Zach paints 3 walls, the total area he paints orange is 88 square feet x 3 = 264 square feet. Zach paints 264 square feet of his bedroom orange.
