Surface Area = [Base Area] + 12 × Perimeter × [Slant Length]

Ryan square pyramid
[Base Area]=10*10=100 feet²
Perimeter=10+10+10+10=40 feet
[Slant Length]=12 feet
Surface Area=100+12*40*12=5860 feet²
Scott square pyramid
[Base Area]=12*12=144 feet²
Perimeter=12+12+12+12=48 feet
[Slant Length]=10 feet
Surface Area=144+12*48*10=5904 feet²

the answer is D.Scott’s pyramid has a greater surface area.
