Surface Area = 2(20*15) + 2(20*9) + 2(15*9)
Surface Area = 2(300) + 2(180) + 2(135)
Surface Area = 600 + 360 + 270
Surface Area = 1230 square feet
Therefore, the surface area of the room that needs to be painted is 1230 square feet.
Surface Area = 6 * (11)^2
Surface Area = 6 * 121
Surface Area = 726 square meters
Therefore, the surface area of a cube with sides measuring 11 meters is 726 square meters.
Surface Area = 2(10*9) + 2(10*7) + 2(9*7)
Surface Area = 2(90) + 2(70) + 2(63)
Surface Area = 180 + 140 + 126
Surface Area = 446 square inches
Amount of cardboard remaining = 500 - 446
Amount of cardboard remaining = 54 square inches
Therefore, Cheryl will have 54 square inches of cardboard left over.
For Monica's 14th birthday, she wants to make over her bedroom. The first phase in the bedroom makeover is painting her room.

Cheryl needs to buy some cardboard to build a box 10 inches long, 9 inches wide, and 7 inches high. If she purchases 500 square inches of carboard. How much will be left over?
(Hint: You must first calculate the surface area of the box. Then, calculate the amount that will remain from the 500 square inches of cardboard)
