Q6 of 52 Page 145

Observe the measures of pots in figure 7.8 and 7.9. How many jugs of water can the cylindrical pot hold?

Height of water jug, HJ = 10cm


Radius of water jug, RJ = 3.5 cm


Volume of conical jug,


Let the number of jugs be n.


Height of cylindrical pot, HP = 10 cm


Radius of pot, RP = 7 cm



Since the water is transferred from pot to ‘n’ number of jugs,


⇒ Volume of pot = n × Volume of jug



On substituting the given values,



⇒ n = 3× 22× 1


⇒ n = 12 cm


∴ The cylindrical pot can hold 12 jugs of water.
