How many 60cmx30cm tiles fit on a wall 8m x2.5m?

Answer 1

Area of each tile = 60*30 = 1800 cm2

Area to be tiles = 8m * 2.5m = 20 m2 = 200000 cm2

Therefore number of tile required = 200000/1800 = 111.11

Therefore a minimum of 112 tiles but that assumes that all offcuts are used - a highly unlikely assumption.
