Square base side = 5cm, height = 14cm
so we can find the volume of cubiod for this
volume of square base pack = lxbxh
= 5x5x14 = 350 cm cube
whereas circle base
volume of cylinder = pi*r^2 * h
= 22/7 * 3.5 * 3.5 *12
= 462 cm cube
so, circular base is greater capacity
difference = 462-350
=112 cm cube
