Step-by-step explanation:
(a)The measure of the side of the cube = 4cm
The T.S.A of a cube = 6l² = 6×(4^2) = 96cm²
The volume of the given cube = l³ = 64cm³
(b) The dimensions of the cuboid = 12×11×15
The T.S.A of the cuboid = 2[(l×b)+ (b×h)+(l×h)]
= 494cm²
The volume of the given cuboid = l×b×h
=(12×11×5)cm³
=660cm³
