Answer 1

416 yd^2

Explanation:

The formula for the surface area of a triangular prism is

`A=2\sqrt{(a+b+c)/(2)((a+b+c)/(2)-a)((a+b+c)/(2)-b)((a+b+c)/(2)-c)}+(a+b+c)h`

where h is the height (10), and a, b and c are the base sides (10, 10, 12).

Answer 2

396 yd^2

Explanation:

8X12=96

(96/2)*2=9

10*10=100

100*3=300

300+96=396
