Answer:
Check the step by step explanation
Step-by-step explanation:
The surface area of a prism can be calculated using the formula below;

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= 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;

L = length of the rectangle
W= width of the rectangle
The area of the rectangle can be calculated using the formula below;

A= area of the rectangle
W= width of the rectangle
