How do you find the surface area of a triangular prism

The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.

Hope this helped :)

Step-by-step explanation:

Find the area to all sides.

Step-by-step explanation:

Find the area of all the triangles (b*h*1/2), and find all the area's of the squares/rectangles (b*h), then add all the areas together.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)
