Question

What is the surface area of this triangular prism? 640 square centimeters 672 square centimeters 960 square centimeters 800 square centimeters

Answer 1

Answer: 672 square centimeters

Explanation:

20 X 10 = 200

(16 X 12)/2 X 2= 192

10 X 12= 120

16 X 10=160

160 + 120 + 192 + 200 =672

Answer 2

`672 \:cm^2`

Explanation:

Find the area of the 2 triangle faces and the 3 rectangle faces, then add the areas together to get the total surface area of the triangular prism.

`(16 * 12 * 1/2) * 2 + (12 * 10) + (16 * 10) + (10 * 20)`

`=672`
