About this calculator
A rectangular prism (cuboid, box) has three pairs of identical rectangular faces. Volume = l × w × h. Surface area = 2(lw + lh + wh). The body diagonal is √(l² + w² + h²) — the longest item that fits diagonally. Used everywhere: shipping boxes, room dimensions, tank capacity.

V = s³. Six equal square faces.
V = (4/3)πr³. Surface area = 4πr².
V = πr²h. Surface area = 2πr² + 2πrh (top + bottom + side).
V = (1/3)πr²h. One-third of the cylinder of same base and height.
V = (1/3) × base area × height. For square / rectangular / triangular bases.
