Question

Your father want to construct a water tank of 30000 litre of water.He wants the tank 6m long and 3m wide.What should be the height of the tank?

Answer 1

volume of cuboid =l*b*h
1 litre=0.001 m^3
30000= ? m^3
its 30m^3
l*b*h=30
6*3*h=30
h=1.66m

Answer 2

Given : Length of the tank = 6m
 Width of the tank = 3m.
Volume of the tank = 30000 l
30000 l = 30m³
⇒Volume of the cuboid = 30m³
⇒lbh = 30m³
⇒6m* 3m* h = 30m³
⇒18m²* h = 30m³
⇒h = 30m³/18m²
∴h = 1.66m
∴The height of the tank = 1.66m
