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.

JudyIf by perimeter you mean the sum of all the sides, there is no formula. If there were to be a formula it would be harder to understand at the educational level that asks such a question than to just add the sides one by one.
or
let x be the width and y be the breadth of the base rectangle.
perimeter=8x+4y

Is a cube is a rectangular prism?
Although there is a separate formula for it, yes, a cube is technically a rectangular prism, and you can use the rectangular prism's formula, because a rectangle is defined as a quadrilateral with four right angles, which a square is.
Surface area of rectangular prism?
The surface area of a rectangular prism can be calculated by adding the areas of all six faces. The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively. This formula accounts for the two faces of each dimension (length, width, and height) on the rectangular prism.
What is the formula for the lateral area of a triangular prism?
Length of prism * perimeter of triangular face.
What is the formula of volume for a rectangular prism?
