Answer:

Sample Response: 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.

Answer:

Check the step by step explanation

Explanation:

The surface area of a prism can be calculated using the formula below;


SA=2B+PH

H = height of the prism

B = Base's area

P = perimeter of the base

They are the same because the same formula is used for the surface area of a rectangular prism and the surface area of a triangular prism.

THE DIFFERENCE BETWEEN THEM IS THIS;

1) for triangular prism,

The perimeter of the base of triangular prism is calculated using g the formula below;


P=a+b+c

P= the perimeter

a,b,c = the length of each of the three making up the triangle

While the AREA of the base of the tria gular prism is calculated using the below formula

A= 1/2 * b* h

A= Area

2) Rectangular prism

perimeter of the base of rectangular prism can be calculated using the formula below;


P=2(L+W)

L = length of the rectangle

W= width of the rectangle

The area of the rectangle can be calculated using the formula below;


A=LW

A= area of the rectangle

W= width of the rectangle
