  2. your area of 69.08 square feet is correct.

    but 69.08 is not 828.96 square inches
    you have to multiply by 144 to change square feet to square inches.
    Why are you changing to square inches anyway? Where does that come in ?

    If one quart covers 100 square feet , and you have 69 square feet to paint, wouldn't you just need 1 quart???
