The answer is the first one A. sss Postulate
The surface area of square pyramid is the sum of the area of all its sides.
If l is the slant height and base is s each then surface area of pyramid is given by:
Surface area = s2+2xsx l
From the given figure in the question:
S=6 cm ,l= 8cm.
Substituting these values in surface area formula we have:
Surface area = 62+2x6x8
Surface area = 36+96
Surface area =132cm2
