Dimensions of a cuboidal water tank are: l = 6 m and b = 5 m and h = 4.5 m

Formula to find volume of tank, V = l×b×h

Put the values, we get

V = (6×5×4.5) = 135

Volume of water tank is 135 m

^{3}Again,

We are given that, amount of water that 1m

^{3 }volume can hold = 1000 lAmount of water, 135 m

^{3}volume hold = (135×1000) litres = 135000 litresTherefore, given cuboidal water tank can hold up to135000 litres of water.
