A powder tin has a square base with side 12 cm and height 17.5 cm. another is cylindrical with diameter of its base 12 cm and height 17.5 cm. Which has more capacity and by how much?
Given,
Side of square base = 12 cm
Height = 17.5 cm
Volume of tin = lbh = 12 × 12 × 17.5 = 2520 cm3
Diameter of cylindrical base = 12 cm
Radius = 
Height of cylinder = 17.5 cm
Volume of tin in cylinder = πr2h = 
Hence,
Capacity of square tin is more by = 2520 – 1980 = 540 cm3
