For tank, breadth = b = 90cm.
height = h = 40 cm.
Capacity of tank = 576 litres.
We lknow that, 1litre = 1000 cubic cm
So, Volume of tank is 576 × 1000=576000 cubic.cm.
Tank is a cuboid.
So, Volume = l×b×h.
Substituting the values,
576000 = 90 × 40 × l
576000 = 3600 × l
l = 576000/3600
l = 160 cm
height = h = 40 cm.
Capacity of tank = 576 litres.
We lknow that, 1litre = 1000 cubic cm
So, Volume of tank is 576 × 1000=576000 cubic.cm.
