15 points What is the surface area of the triangular prism below? A. O 13,272 in2
B. O 15,624 in 2
C. 16,800 in?
D. 14,448 in2

answer. d.289 hope that

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
