Step-by-step

  1. V = l × w × h = 10 × 6 × 4 = 240.0000.
  2. Surface area = 2(lw + lh + wh) = 248.0000.
  3. Diagonal = √(l² + w² + h²) = 12.3288.

How to use this calculator

  • Enter length, width, height.
  • Read volume + surface area + diagonal.

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.
