Answer:

60

Explanation:

To find the volume of this object, find The volume of the cuboid as a whole (ignore the hole as if it's not there) and then remove the volume of the hole (cuboid) from it.

Volume of whole solid = 9 × 6 × 5/4 = 67.5 ft³

For the invisible solid (hole part), you already have width and height, you can find the length too. Length = 9 - (2+3) = 9 - 5 = 4 ft

Volume of invisible solid = 5/4 × 4 × 5/2 = 12.5 ft³

Required volume = 67.5 - 12.5 = 55 ft³
