(a) The volume of the soil required is 48 ft³
(b) Trevor has 36 ft³ of soil
<u>Explanation:</u>
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
