Add up the sides.
width*height*length=perimeter of a rectangular prism! :)
There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
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.
It is the perimeter of a triangle times the length of the prism (in square units).
The same way you find the perimeter of a rectangle, add the side lengths
You look at the edge of the triangular prism and count the points
1/2 AP where A=apothem and P= perimeter
Side1 + Side2 + Side3
The lateral area of a prism can be calculated using the formula: Lateral Area = Perimeter × Height. Given a height of 6 m and a perimeter of 4 m, the lateral area would be 4 m × 6 m = 24 square meters. Therefore, the lateral area of the prism is 24 square meters.
It is p*h square units.
To find the lateral area of a prism, you first need to identify the perimeter of the base and then multiply it by the height of the prism. For a prism with base dimensions of 4 and 6 (assuming these are the lengths of the sides of a rectangular base) and a height of 8, the perimeter of the base is (2(4 + 6) = 20). The lateral area is then calculated as ( \text{Lateral Area} = \text{Perimeter} \times \text{Height} = 20 \times 8 = 160) square units.
