Question

A cuboid is of dimensions $l=3cm,b=2cm,h=2cm$. How many cubes of 1 cm side can be cut out of it ?

• A. $12$
• B. $6$
• C. $4$
• D. $3$

Answer 1

Answer: (A)

$12$

$l=3cm,b=2cm,h=2cm$

Volume of cuboid $=l\times b\times h=3\times 2\times 2=12{cm}^3$

Edge of cube $=1cm$

Volume of 1 cube $=a^3={\left(1\right)}^3=1{cm}^3$

Number of cubes $=\frac{Volumeofcuboid}{Volumeof1cube}=\frac{12}{1}=12$
