Rectangular Prism Volume Calculator

Find the volume of a box or cuboid. Enter the three dimensions below to get the total cubic capacity and surface area.

Volume (V) = Length × Width × Height
If Length=10, Width=5, Height=2: V = 10 * 5 * 2 = 100 cubic units

What is a rectangular prism?

A rectangular prism is a three-dimensional solid shape which has six faces that are all rectangles.

What is the volume formula for a rectangular prism?

The volume is calculated by multiplying the length, width, and height: V = l × w × h.

How do I calculate the surface area?

The total surface area is the sum of the areas of all six faces: A = 2(lw + lh + wh).

Is a cube a rectangular prism?

Yes, a cube is a special type of rectangular prism where all six faces are squares (length = width = height).
