Problem
A student claims that when a solid is melted and completely recast into new identical solids, the total mass of the product is the same as that of the original solid, provided no material is lost.
(i) Give a reasoned explanation to support or refute the student's claim.
(ii) The student melts a solid of volume 960 cm3 and wants to cast identical cubes of side 4 cm. Justify, with suitable calculation, whether 14 such cubes can be obtained without wasting material.
