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