Question

Find the number of cubes of side 2 cm required to make a cube of side 6 cm.

• A. 27
• B. 32
• C. 42
• D. 37

Answer 1

The correct option is A 27

Given a cube of side $2cm$.


For making the side of the cube of length $6cm$, we need $3$ cubes of side $2cm$ each.


Similarly, to make the breadth and height of the cube as 6 cm, we need arrangement of 3 cubes each of side $2cm$ as shown below.


Therefore, the total number of cubes needed is 27.
