Q:

# How do you calculate the perimeter of the base of a rectangular prism?

A:

To obtain the perimeter of a rectangular base, add all the sides using the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. You need ruler or a tape measure, a pen and a piece of paper. The process takes just a few minutes.

1. Determine the dimensions of the base

The base of a rectangular prism has four sides. The two lengths of the base are equal and the two widths are equal as well. Measure the sides using a ruler or a tape measure.

2. Multiply the value of each dimension by 2

Multiply the length by 2. Do the same with the width.

Add the values obtained from the previous step. The sum is the perimeter of the base of a rectangular prism.
