Question 2
A cuboidal water tank is 6 m long, 5 m wide and 4.5 m deep. How many litres of water can it hold? $(1m^3=1000l)$

The given cuboidal water tank has its length (l) as 6 m, breadth (b) as 5m, and height (h) as 4.5 m.

Volume of the tank = $l\times b\times h$

$=(6\times 5\times 4.5)m^3=135m^3$

Amount of water that $1m^3$ volume can hold =1000 litres

Amount of water that $135m^3$ volume can hold = $(135\times 1000)litres=135000litres$

Therefore, such tank can hold up to135000 litres of water.
