Question

The number of cubes of side 3 cm that can be cut from a cuboid of dimensions 9 cm × 9 cm × 6 cm, is:

• A. 26
• B. 9
• C. 10
• D. 18

Answer 1

The correct option is D 18

Dimension of the cuboid $=9cm\times 9cm\times 6cm$
Edge of the cube $=3cm$
So, the number of cubes of sides 3 cm, that can be cut from the cuboid,
$\Rightarrow \frac{9cm\times 9cm\times 6cm}{3cm\times 3cm\times 3cm}=18$
