Question

Shishir is making a cube of side 6 cm using cubes of sides 2 cm. How many such cubes are needed?

• A. 216
• B. 27
• C. 9
• D. 36

Answer 1

The correct option is B 27

Given a cube of side 2 cm.

First for making the length 6 cm, we need 3 cubes of 2 cm each.

Similarly, complete the breadth and height of the cube with 3 and 3 cubes repectively of 2 cm.

So the total number of cubes needed is 27 to make a cube of side 6 cm.
