Making rather an unjustified assumption that they are 16 INCH by 16 INCH tiles,
each tile has an area of 1.33... *1.33... sq ft = 1.77... sq ft
80sq ft would therefore rewuire 80/1.77... = 45 tiles.
This assumes that the 80 square feet is in the shape that accommodates 16"*16" tiles or that all offcuts are utilised. In real life, you should allow for at least 5% wastage - more if you are not an expert.
