the net of a square pyramid is shown:

what is the surface area of the figure?
0.5625 square inch
0.7625 square inch
1.5625 square inches
1.7625 square inches

Given that the net of the square pyramid is as shown above, the surface are of the pyramid will be given by:
SA=(number of triangles)*(area of triangle)*(area of square base)
area of one triangle will be:
A=1/2*base*height
A=1/2*0.8*0.75
A=0.3 sq. inches

area of the square base will be:
A=0.75*0.75
A=0.5625
Therefore the surface area will be:
SA=4*0.3*0.5625
SA=0.675 sq. inches

Ithink the answer is c just trying to others
