Question

The figure below is a net for a square pyramid. What is the surface area of the square pyramid, in square inches?

Answer 1

Answer: your answer is 266.44 square inches

Explanation: Triangles:

6.1x7.6=46.36in

Each triangle is 46.36in

46.36x4=185.44in

Rectangle:

9x9=81in

The rectangle is 81in

All together:

185.44+81=266.44in

So the square is the easiest do 4×4=16

The triangles its just Base×Height/2 in that order so 4×3=12/2=6

Mulitply 6 by 4 because there's 4 triangles and add 16 so 6×4=24+16=40

Hope this helped:)

Answer 2

183.89

Explanation:

S = square area + area of 4 triangles =

7.1^2 + 4*0.5*9.4*7.1 = 183.89
