To calculate the capacity of a water tank we will find the volume of the water tank in cubic meters and multiply it by 1000 to convert it into litre.
How to calculate the capacity of a rectangular water tank?
For the capacity of a rectangular water tank we calculate the volume of the rectangular water tank L✕B✕H in cubic metre and multiply it by 1000 to convert it into litre.
Let us take an example for better understanding:
Q- The length, breadth, and height of a rectangular water tank are 4m, 2m, and 3m respectively. Find its volume and capacity in litres.
Solve:
Volume of a rectangular tank formula = L✕B✕H
= L✕B✕H
= 4m✕2m✕3m
= 24 cubic metres.
The capacity of rectangular water tank = Volume of tank✕1000
= Volume of tank✕1000
= L✕B✕H✕1000
= 4m✕2m✕3m✕1000
= 24✕1000
= 24000 litres.
How to calculate the capacity of a circular water tank?
To calculate the capacity of a circular water tank we will find the volume of cylinder Ï€r²h in cubic metres and multiply it by 1000 to convert it into litre.
Take an example for better understanding:
Q- Calculate the volume and capacity of a circular water tank of radius 2m and height 7m.
Solve:
The volume of cylindrical tank formula = Ï€r²h
= Ï€r²h
= 22/7✕2✕2✕7
= (22✕2✕2✕7)/7
= 88 cubic meter
The capacity of circular water tank = Ï€r²h✕1000
= Ï€r²h✕1000
= 22/7✕2✕2✕7✕1000
= (22✕2✕2✕7✕1000)/7
= 88000 litres
