One litre of paint covers 16m2 with one coat. Harry paints everything with 2 coats. How many square meters can he paint twice with 7L of paint?
-
square metres painted by 1 litre paint with one coat = 16
square metres painted by 1 litre paint with double coat = 16/2=8
square metres painted by 7 litre paint with double coat = 8*7=56m^2
square metres painted by 1 litre paint with double coat = 16/2=8
square metres painted by 7 litre paint with double coat = 8*7=56m^2

1-litre paint covers(1-coat) = 16 m^2
1-litre paint covers(2-coats) = 16/2 = 8 m^2
7-litre paint covers(2-coats) = 7*8 = 56 m^2 >==========< ANSWER
1-litre paint covers(2-coats) = 16/2 = 8 m^2
7-litre paint covers(2-coats) = 7*8 = 56 m^2 >==========< ANSWER

One L = 16m2
Therefore, 7L = 7*16 m2, or 112 square meters. However, we know that he uses two coats, so we have to divide that by two, which gives us 56 square meters.

1 liter will cover 16m² with one coat or 8 m² with two coats. 7 liters would cover 7*8 = 56 m² with two coats.
