An empty box is shaped like a rectangular prism. The box has a base area of 9/10 square foot and a height of 1/3 foot. How much packing material is required to fill the box?

a. 3/10 ft^3

b. 1/10 ft^3

c. 1/3 ft^3

d. 2/3 ft^3

Since we already know the base area, we simply have to multiply it by the height to get the volume of the box (how much packing material it can contain)

9/10 x 1/3

9 x 1 = 3

10 3 10 (I cancelled the 9 and 3 and made them 3 and 1 respectively)

The answer is 3/10 ft³
