Formula for Surface Area and Volume of a Triangular Prism
LA = Lateral Area (this is the Area without the bases)
Find the SA of a Triangular Prism: with an equilateral triangle base, whose sides measure 5 inches each and the triangle's h = 7.
The height of the entire Prism is 10 in. Follow the SA formula! Can you do it?

or SA = LA + 2B

Multiple Choice
What is the surface area of this figure? Use SA = LA + 2B
(Find the Laderal area first then add the Area of the 2 Bases.
To find the LA:
Find the Perimeter of the base (4 x10) then multiply that by the height of the prism (40 x 15)
Next:
Find the Area of both bases (2 x 100) and add that to the LA
OR:
You can open the figure to create a NET and find the SA.
11
Find the LA first then find Area of the Bases.
