Hi . w = 2.5m, l = 3.6m, h = 2m Surface = 2lw + 2lh + 2wh S = 2(3.6)(2.5) + 2(3.6)(2) + 2(2.5)(2) = 18 + 14.4 + 10 = 42.4m^2 75¢/square meter yes cost of painting the outer surface = 42.4*.75/m = $31.80 Wish You the Best in your Studies.

Why @ewatrr introduces square yards and converts square meters to square yards,
