Add up all of the lengths of the edges adjacent to one of the bases.
Perimeter = 2 x (length+width). You add the length to the width and multiply the sum by two.
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.
surface area=(perimeter of base)x(height of the shape)+(area of the base)x(2)
To find the surface area of a prism, first calculate the area of the two bases and then the areas of the rectangular faces connecting the bases. The total surface area is the sum of the base areas and the lateral area. Specifically, use the formula: Surface Area = 2 × Base Area + Lateral Area, where the lateral area is the perimeter of the base multiplied by the height of the prism. Ensure you use consistent units throughout your calculations.
divide perimeter by 6.
12 the base times the height
12 the base times the height
width*height*length=perimeter of a rectangular prism! :)

L=PH L=PH Lateral Area= (Perimeter of the base)(the height of the figure)
To find the perimeter of the base, you must add all the numbers on the base together!
divide perimeter by 6.
Height = (Perimeter/2) - Base

perimeter (P)=2(length+base) find length, area = length * base = (p/2-base)*base
