Question

The description for a certain brand of house paint claims a coverage of 475 ft²/gal.

(a) Express this quantity in square meters per liter.
(b) Express this quantity in an SI unit.
(c) What is the inverse of the original quantity?

Answer 1

(a) 11.66 square meters per liter

(b) 11657.8 per meters

(c) 0.00211 gal per square feet

Step-by-step explanation:

(a) 475ft^2/gal = 475ft^2/gal × (1m/3.2808ft)^2 × 1gal/3.7854L = 11.66m^2/L

(b) 475ft^2/gal = 475ft^2/gal × (1m/3.2808ft)^2 × 264.17gal/1m^3 = 11657.8/m

(c) Inverse of 475ft^2/gal = 1/475ft^3/gal = 0.00211gal/ft^3
