What is the formula for a perimeter of a rectangular prism?

The formula for the perimeter of a rectangular prism is 2(length + width) + 2(length + height) + 2(width + height). This formula calculates the total distance around the three-dimensional shape by adding the distances of all the edges. The perimeter is important for determining the amount of material needed to enclose the rectangular prism or for calculating the distance around it.
