Question

A water tank is 1.4 m long, 1m wide and 0.7m deep. Find the volume of the tank in litres.

Answer 1

$\text{Length of the tank}\left(l\right)=1.4m=140\text{cm}$
$\text{Breadth of the tank}\left(b\right)=1m=100\text{cm}$
$\text{Depth of the tank}\left(h\right)=0.7=70\text{cm}$
$\text{Volume of the tank}=l\times b\times h$
$=(140\times 100\times 70){\text{cm}}^3$
$=\frac{(140\times 100\times 70)}{1000}\text{litres.}$
$=980\text{litres}$
