MCQ
Volume of a rectangular box $($cuboid$)$ with length $= 2ab,$ breadth $= 3ac$ and height $= 2ac$ is:
  • ✓
    $ 12 a^3 b c^2 $
     
  • B
    $ 12 a^3 b c $
     
  • C
    $ 12 a^2 b c $
     
  • D
    $ 2 a b+3 a c+2 a c $
✓

Answer

Correct option: A.
$ 12 a^3 b c^2 $
 
We know that, volume of a cuboid $=$ Length $\times $ Breadth $\times $ Height
$= 2ab \times 3ac \times 2ac$
$= (2 \times 3 \times 2)ab \times ac \times ac$
$= 12 \times a \times a \times a \times b \times c \times c$
$= 12 a^3 b c^2 $
