Add all four sides.
If you don't know the side lengths then you must know either {height and diagonal from top to bottom-corner} or {diagonal from bottom-center to bottom-corner}. If you know the first two, then use Pythagoras' Theorem to find the second. Now, double that and use Pythagoras' Theorem to find the side length.

How do you find the perimeter of a base of a rectangular prism?
12 the base times the height
How do you find the perimeter of a rectangular prism?
width*height*length=perimeter of a rectangular prism! :)
How do you find the lateral surface of a triangular prism?
The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.
How do you find the lateral area of a rectangular prism?
L=PH L=PH Lateral Area= (Perimeter of the base)(the height of the figure)
How do you find surface area and volume of an octagonal prism?
If the octagon at the base is regular, the side of the octagon is s and the height of the prism is h, the area of each octagonal base (Ab) is Ab = 2(√2 +1) s2 The perimeter of the octagon is P = 8s Then the surface area of the prism is As = 2 Ab + Ph The volume of the prism is V = Ab h
How do you find the surface area of a square prism?
Okay, the last person who edited this, totally screwed up. The formula to find the surface area of a square prism is 2B+Ph, multiply the length of the width of the base to get the area, then multiply that by two. After you have multiplied the base twice, et the perimeter of the base and multiply it by the height of the square prism.
How do you find perimeter of the base of a rectangular prism?
12 the base times the height
How do you find the perimeter of a base of a rectangular prism?
12 the base times the height
How do you find the perimeter of a square prism?

How do you find the perimeter of a base of a pentagonal prism?
1/2 AP where A=apothem and P= perimeter
How do you find the perimeter of the base in a retangular prism?
The same way you find the perimeter of a rectangle, add the side lengths
How do you find the surface area of a right prism?
2*area of a base + length*perimeter of base.
How do you find the surface area of trapezoidal prism?
Surface Area = 2 × Base Area + Base Perimeter × Length
How do you find the perimeter of base for rectangular prisms?
Add up all of the lengths of the edges adjacent to one of the bases.
How do you find the TSA of a prism?
TSA=total surface area=2Xarea of base + perimeter of baseXheight
How do you find a base of a prism?
first u find the perimeter and then u get the base the u have to find the area of the base and that the gives u b the base of a prism
