Question:

A cube has sides that are 4 cm each, and the dimensions of a cuboid are 2 cm × 3 cm × 4 cm. Find the positive difference between the volume of the cube and that of the cuboid.

Options:

40 cm3

120 cm3

20 cm3

60 cm3

Correct Answer:

40 cm3

Explanation:

We know that,

Volume of a cube = (Side)3

Volume of a cuboid = Length × Breadth × Height

Side of a cube = 4cm

Dimensions of a cuboid = 2 × 3 × 4 cm

Volume of the cube = 43 = 64 cm3

Volume of the cuboid = 2 × 3 × 4 = 24 cm3

Now, the positive difference between the volume of the cube and that of the cuboid = 64 - 24 = 40 cm3
