Question
Obtain the volume of rectangular boxes with the following length, breadth and height, respectively.
$2 p, 4 q, 8 r$
✓

Answer

We have, length $=2 p$, breadth $=4 q$ and height $=8 r$
$\therefore \text { Volume of rectangular box } $
$=\text { Length } \times \text { Breadth } \times \text { Height } $
$=(2 p) \times(4 q) \times(8 r) $
$=(2 \times 4 \times 8) \times(p \times q \times r) $
$ =64 p q r$
