Question

Which expression can be used to find the surface area of the following triangular prism?

Answer 1

Answer:

1. The answer is actually, "C"

Step-by-step explanation:

I mean to offence to the other person, but sadly I must prove them wrong.

Let's start by finding the area of the triangles.

Triangles:

• Area = 1/2 · base · height
• = 1/2 · 4 · 3
• = 1/2 · 12
• = 6

There are two triangle faces with an area of 6 square units.

So, we add it twice.

Left rectangle:

• Area = base · height
• = 3 · 10
• = 30

Center rectangle:

• Area = base · height
• = 4 · 10
• = 40

Right rectangle:

• Area = base · height
• = 5 · 10
• = 50

Finally, we add the area of them all.

Expression:

6 + 6 + 30 + 40 +50.
