Triangular Prism:

Formulas:

-A = b x h/2

-A = l x w

TSA= A1 + A2 + A3 + A4 + A5

To the find the total surface area of a triangular prism you have to find the area of each of the five faces. After finding all the areas, you then have to add all of them up to get the TSA.

Cylinder:

Formulas:

- r = d/2 or d = 2r

- C = π d

- A = π x r x r

- A = l x w

TSA = A1 + A2 + A3

To find the total surface area of a cylinder you have to find the area of each of the three faces. After that you have to add up the areas of each faces and you will then get your TSA.

Rectangular Prism:

Formula: A = l x w

TSA = A1 + A2 + A3 + A4 + A5 + A6

To find the total surface area of a rectangular prism you have find the area of each of the six faces. After finding the areas of each faces, you add it all up to get the total surface area or the TSA.
