Volume and Capacity
Volume refers to the amount of space occupied by an object and capacity refers to the quantity that a container holds.
Ex: If an oil tank holds 100000 cm3 of oil then the capacity of the oil tank is 100000 cm3.
We can measure the capacity in terms of liters also.
1 mL = 1 cm3
1 L = 1000 cm3
1 m3 = 1000000 cm3 = 1000 L
Problem: A milk tank is in the form of cylinder whose radius is 1.5 m and length is 7 m. Find the quantity of milk in liters that can be stored in the tank.
Given: Radius of cylindrical tank (r) = 1.5 m
And Height of cylindrical tank (h) = 7 m
Volume of cylindrical tank = πr2 h
= 22/7 * 1.5 * 1.5 * 7
= 22 * 1.5 * 1.5
= 49.5 cm3
= 49.5 * 1000 liters [Since 1 m3 = 1000 liters]
= 49500 liters
Hence, the required quantity of milk is 49500 liters.
