100
How do you find total surface area?
Find the area of the entire figure and add them all up
100
How is the lateral surface area different than the total surface area?
You do not include the base(s) in lateral surface area
200
What is the formula for volume of a triangular pyramid and how would you solve for "B"
V= 1/3(Bh)
B=bh/2 (because it's a triangular base)
200
What does "B" stand for?
Area of the base

Find the total surface area of the triangular prism
area of rectangles= bh
area of rectangles= 5 x 10
area of rectangles = 50
three rectangles = 150
area of triangles = 1/2bh
area of triangles= 1/2(5x4)
area of triangles=1/2(20)
area of triangles=10
two triangles= 20
area of rectangles + area of triangles= 150 + 20
