What Volume of Soil, in cubic feet , does Trevor need?

Trevor only has enough soul to fill the flower box 1 foot from the top. How much soil, in cubic feet, does he have?

(a) The volume of the soil required is 48 ft³

(b) Trevor has 36 ft³ of soil

Explanation:

The trevor is made up of 2 cuboids

Dimensions of cuboid 1 = 6 ft , 3 ft and 2 ft

Dimensions of cuboid 2 = 2ft, 3 ft, 2 ft

(a)

Volume of cuboid 1 = 6 X 3 X 2 ft³

                                = 36 ft³

Volume of cuboid 2 = 2 X 3 X 2 ft³

                                 = 12 ft³

Total volume = 36 + 12 ft³

                      = 48 ft³

Therefore, the volume of the soil required is 48 ft³

(b)

If Trevor just have soil that could fill box 1, then the volume of soil is 36 ft³
