MCQ
Volume of a rectangular box (cuboid) with length $= 2ab,$ breadth $= 3ac$ and height $= 2ac$ is:
- ✓$12a^3bc^2$
- B$12a^3bc$
- C$12a^2bc$
- D$2ab + 3ac + 2ac$
✓
Answer
Correct option: A.
$12a^3bc^2$
We know that, volume of a cuboid $=$ Length $\times$ Breadth $\times$ Height
$= 2ab \times 3ac \times 2ac$
$= (2 \times 3 \times 2)ab \times ac \times ac$
$= 12 \times a \times a \times a \times b \times c \times c$
$= 12a^3bc^2$
$= 2ab \times 3ac \times 2ac$
$= (2 \times 3 \times 2)ab \times ac \times ac$
$= 12 \times a \times a \times a \times b \times c \times c$
$= 12a^3bc^2$
