a metallic cuboid of dimensions 27x18x12 m is melted.find the minimum amount of the volume of molten metal which should be added to mould it into a cube whose edge is 'a' cm where a is an integer.  Choose the correct choice from the following answers:	A) 16 m	B) 17 m	C) 18 m	D) 19 m	E) 15 m
volume of cuboid = 27*18*12 = (27*27*8)= (3*3*2)^3= 18^3   so no amount of the volume of molten metal should be added to mould it into a cube whose edge is 'a' cm where a is 18 m.   ANSWER:18 m
