Which expression can be used to find the surface area of the following square pyramid? Choose 1 Choose 1 (Choice A) A 4+64+64, plus, 6 (Choice B) B 4+3+3+34+3+3+34, plus, 3, plus, 3, plus, 3 (Choice C) C 4+6+6+6+64+6+6+6+64, plus, 6, plus, 6, plus, 6, plus, 6 (Choice D) D 4+3+3+3+34+3+3+3+3

i can answer this question sweetie!

step-by-step explanation:

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.

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
