Question

Find the volume of the following:
(i) A cuboid whose dimensions are $1.6m\times 0.8m\times 0.4m$
(ii) A cube whose each edge in $9cm$.
(iii) A cylinder whose radius is $6.3cm$ and height is $12cm$.

Answer 1

$\left(i\right)$ A cuboid whose dimensions are $1.6m\times 0.8m\times 0.4m$

Volume of a cuboid$=length\times breadth\times height=1.6\times 0.8\times 0.4=0.512‬m^3$

$\left(ii\right)$ A cube whose each edge in $9cm$.

Volume of a cube$=edge\times edge\times edge=9\times 9\times 9=729{cm}^3$

$\left(iii\right)$ A cylinder whose radius is $6.3cm$ and height is $12cm.$

Volume of a cylinder$=\pi r^{2}h=\pi \times 6.3\times 6.3\times 12=476.28‬\pi {cm}^3$
