What are two ways you can find the surface area of a prism?

Answers

Answer 1

Answer: 1. If the matching ends are triangles, find the area of the triangle (A=1/2bh)
2. If Matching ends are rectangles/squares, find the area of the rectangle/square (bh)
Hope that was helpful!!!

Answer 2

Answer: The total surface area of a prism is the sum of the area of all of its sides.

The surface area = (2 * area of base) + (perimeter of base * height)

If the base is a rectangle or square you can use this formula:
SA = 2LW + 2(L+W)H = 2LW + 2HL + 2HW = 2(LW + LH + HW)

If the base is a circle, use this formula:
SA = 2πr² + 2πrh

If the base is a triangle, this formula will come in handy:
SA = bh + ( $\sf{s_1 + s_2 + s_3}$ )h
where s₁, s₂, and s₃ are the three sides of the triangle.

Answer:

9 1/6

Step-by-step explanation:

2 1/2 * 3 2/3

Change each mixed number to an improper fraction

2 1/2 = (2*2+1) /2 = 5/2

3 2/3 = (3*3+2)/3 =11/3

5/2*11/3 = 55/6

Now we change back to a mixed number
