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.
To find the width of the rectangular side of a pentagonal prism, we need to know the height of the prism or additional dimensions related to the rectangular sides. The perimeter of the base, which is the pentagon, is 45 cm, but without the height or specific dimensions of the rectangular sides, we cannot determine the width. If you provide the height or more details, I can help you calculate the width.
12 the base times the height
12 the base times the height
Perimeter = 2 x (length+width). You add the length to the width and multiply the sum by two.
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!

To find the lateral surface area of a triangular prism, first calculate the perimeter of the triangular base. Then, multiply the perimeter by the height (length) of the prism. The formula can be expressed as: Lateral Surface Area = Perimeter of Base × Height. This gives you the total area of the three rectangular faces that connect the triangular bases.
divide perimeter by 6.
