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

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

We know that,
Volume of tank
= l x b x h
= (6 x 5 x 4.5) \(m^2\)
= 135 \({m}^{2}\)

But, Amount of water that 1 \({m}^{2}\) volume can hold = 1000 litres

Thus, Amount of water that 135 volume can hold
= (135 x 1000) litres = 135000 litres

Therefore, such tank can hold up to 135000 litres of Water.
