How is the process of finding the surface area of a rectangular prism the same as finding the surface area of a triangular prism? How is it different?

ANSWER:
For both prisms, you can draw a net to help you find the areas of the faces. Add the areas together to find the surface area. A rectangular prism has only rectangular faces, and you use the formula bh to find area. A triangular prism has triangular and rectangular faces, and you use the area formula bh for rectangular faces and the area formula 1/2bh for triangular faces.

Step-by-step explanation:

we know that

The surface area of a prism is given by the formula

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

For both prism the formula is the same

How is it different?

Rectangular prism

The area of the base is given by the formula

-----> is the area of rectangle

where

L is the length and W is the width of rectangle

The perimeter of the base is given by

---> is the perimeter of rectangle

The height H is the same in both cases

Triangular prism

The area of the base is given by the formula

-----> is the area of the triangular base

where

b is the base of triangle and h is the height of triangle

The perimeter of the base is given by

---> is the perimeter of triangle

where

a, b and c are the length sides of triangle

The height H is the same in both cases
