width*height*length=perimeter of a rectangular prism! :)
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.
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.
L=PH L=PH Lateral Area= (Perimeter of the base)(the height of the figure)
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.
surface area=(perimeter of base)x(height of the shape)+(area of the base)x(2)
The base of a rectangular prism is a rectangle. The area of a rectangle is length times width.
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.
Volume of rectangular prism = area of base x height
