The description for a certain brand of house paint claims a coverage of 460 ft2/gal. (a) express this quantity in square meters
Angelina_Jolie [31]

Given 460 ft^2/gal

a) convert it into m^2/l

=> It means ft^2 -> m^2 and gal -> l

1 ft = 0.3048 m

1 ft^2 = 0.092903 m^2

1 gal = 3.78541 l

460ft^2= [tex]460\frac{ft^2}{gal} = \frac{42.7354m^2}{3.78541l} = 11.2895m^2/l m^2[/tex].

b.  11.2895\frac{m^{2} }{l} *1000\frac{l}{m^3} =11289.5 m^{-1}

c.Given=  460\frac{ft^2}{gal}

To find inverse, divide it by 1.

Inverse- \frac{1}{460} \frac{gal}{ft^2}
