How many bullet can be made out of a cube of lead, whose edge measures 22 cm, each bullet being 2 cm in diameter?
Volume of a cube = side3
Volume of a sphere = (4/3)πr3
Given, edge of a cube is 22 cm and the bullet are of 2 cm diameter
Thus, volume of the cube = 22 × 22 × 22 = 10648 cm3
Volume of each bullet = (4/3) × (22/7) × 13 = 4.19 cm3
No. of bullet that can be made out of the cube of lead = 10648/4.19 = 2541
