The Total solution for NCERT class 6-12
Given,
The radius of eachspherical lead shot = r = 4/2 = 2 cm
Volume of eachspherical lead shot = 4/3 πr3 = 4/3 π 23 cm3
Edge of the cube = 44cm
Volume of the cube =443 cm3
Thus,
Number of sphericallead shots = Volume of cube/ Volume of each spherical lead shot
= 44 x 44 x 44/ (4/3 π23)
= 2541
