If 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
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.
Length of prism * perimeter of triangular face.
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
the formula is length x width x height
its not i dont no why
69+39 degrees happy now?
width*height*length=perimeter of a rectangular prism! :)
Depends whether you want the formula for surface area, volume, perimeter, size of sphere it would fit into etc... Please clarify next time.
Because it is a rectangular prism and it has volume and area also mass and perimeter
The volume of a rectangular prism can be found by the formula: volume=length*width*height
The formula for the area of a rectangular prism is A= 2(wL+hL+hw). A refers to area, w is the width of the prism, h refers to height, and L is the length of the prism.

The answer depends on what information you do have about the prism.
In any case, the perimeter of a rectangular prism of length L units, width W units and height H units, is 4*(L + W + H) units

Add up all of the lengths of the edges adjacent to one of the bases.
I am not sure that a rectangular prism is in any position to care!
