Question

A water tank is 35 metres long, 15 metres wide and 4 metres deep.It is half filled. How many litres of water does it contain now?

• A. 10,40,000 litres
• B. 10,60,000 litres
• C. 10,50,000 litres
• D. 10,30,000 litres

Answer 1

The correct option is C

10,50,000 litres

Volume of water = Volume of tank

Given: Length = 35 m, Width= 15 m

Depth = 4 m

Half filled $\Rightarrow height=\frac{depth}{2}$

$\Rightarrow height=\frac{4}{2}$

$\Rightarrow height=2m$

Volume $V=35\times 15\times 2=1050cubicmetres$

1 cubic metre = 1000 litres

1050 cubic metres= $1050\times 1000litres=10,50,000litres$
