Question

Find the volume of the given cuboid. Volume of each cube is $1c{m}^3$.

• A. $18c{m}^3$
• B. $12c{m}^3$
• C. $16c{m}^3$
• D. $10c{m}^3$

Answer 1

The correct option is B $12c{m}^3$

Given:
A cuboid made of cubes.
Volume of each cube, $V=1c{m}^3$

The rectangular prism has 4 unit cubes in 3 layers. In other words, it is made of 12 cubes.
So, the volume of the cube is:
$V^{\prime }=12\times 1{cm}^3=12{cm}^3$
