b=side of base=5ft=60in; h=height=8ft=96in
Slant height=s=sqrt%28%28%281%2F2%29b%29%5E2%2Bh%5E2%29= sqrt%2830%5E2in%5E2%2B96%5E2in%5E2%29=sqrt%2810116%29=100.6in (Each side is a triangle with base=60 inches and height=100.6 inches)
Area of each side =1/2bs=1/2(60in)(100.6in)=3017.35 sq in=20.95 sq ft
Area of all sides =3017.35sq in*4=12069.4 sq in=83.8 sq ft
Area of floor=5ft*5ft=25 sq ft
ANSWER: Total with floor would be 108.8 sq ft
