Question

The number of cubes of side 3 cm that can be cut from a cuboid of dimensions $9cm\times 9cm\times 6cm,$ is

• A. 9
• B. 10
• C. 18
• D. 20

Answer 1

The correct option is C

18

$\text{Dimensions of the cuboid}=9cm\times 9cm\times 6cm$

$\text{Edge of a cube}=3cm$

$\therefore \text{No. of cubes can be cut out of the cuboid}$ $=\frac{9\times 9\times 6}{3\times 3\times 3}$

$=3\times 3\times 2=18$
