What is the surface area of the square pyramid?
2 answers:
10*10
0.5*10*12
340cm^2
Hope this helps
The base is a square, therefore all the sides of the base are the same. This also means all the triangles have the same area.
10*10 = 100 cm^2 for the base
0.5*10*12 = 60 cm^2 for each triangle
100 + 4(60) = 340 cm^2
