Question

Someone please answer!! What is the surface area in yards squared of the triangular prism shown below?

Answer 1

Answer:

1,120 yd²

Step-by-step explanation:

Surface area of the triangular prism = (bh) + (s1 + s2 + s3)*L

Where,

b = 15 yd

h = 8 yd

s1 = 17 yd

s2 = 15 yd

s3 = 8 yd

L = 25 yd

Substitute

Surface area = (15*8) + (17 + 15 + 8)*25 = 120 + 40*25 = 120 + 1,000

Surface area = 1,120 yd²
