Calculate volume, surface area and space diagonal of a rectangular cuboid.
A cuboid (rectangular prism) has three pairs of rectangular faces. Volume = l×w×h, surface area = 2(lw + lh + wh), space diagonal = √(l²+w²+h²).
Volume
V = l × w × h
Surface Area
SA = 2(lw + lh + wh)
Yes — a cube is a cuboid where all three dimensions are equal.
You cannot — volume alone does not uniquely determine the three dimensions. You need at least two of the three.
