What is the volume of a rectangle?

A rectangle is a two dimensional shape, so it doesn't have volume. If you wanted to calculate the area of the rectangle, you simply multiply the length by the width.

If, however, you wanted to calculate the volume of a 3D rectangle (also known as a cuboid), you would multiply the length, width, and height together.

Use the simple formula:Vol = 0

A rectangle is a 2-dimensional figure and therefore has no volume which is a concept which is relevant to 3-dimensional objects.
