Solution
The correct option is D 96 cubic cm To find the volume, let's devide the figure into different solids.
Total volume = Volume of two cubes on the top + Volume of cuboid at bottom.
Volume of cube
= Length × Width × Height
For a cube: length = width = height
Volume of the cube
= 3 × 3 × 3 = 27 cubic cm
Volume of the cuboid
= Length × Width × Height
= 2 × 7 × 3
= 42 cubic cm
