Question

The net of square pyramid is shown below. What is the surface area of the pyramid ?

Answer 1

this is the answer
192

Answer 2

To find surface area, find the area of the net like you would for a composite figure.
For the square, area is length times width.
8*8=64
For the triangles, area is bh/2
8*8/2=32
Since there are four triangles of the same area, multiply by 4.
32*4=128

Add these values
128+64=192 cm^2

Final answer: D
