Two cans have the same height equal to 21 cm. One can is cylindrical, the distance of whose base is 10 cm. The other can has square base of side 10 cm. What is the difference in their capacities?

Question: Two cans have the same height equal to 21 cm. One can is cylindrical, the distance of whose base is 10 cm. The other can has square base of side 10 cm. What is the difference in their capacities?

Solution:
Difference in capacities = Volume of cubodial can - Volume of cylindrical can
= [ (10 × 10 × 21) - ((22/7) × 5 × 5 × 21))] cm³
= (2100 - 1650) cm³
= 450 cm³
