Question

Generally, one gallon of paint can cover 350 ft².

How many gallons would be required to cover a wall that measures 144 ft2? "Round your answer to the correct number
of significant figures.

Answer 1

To cover a wall that measures 144 ft², you would need:

0.41 gallons of paint (rounded to two significant figures).

This is calculated by dividing the area of the wall (144 ft²) by the area that one gallon of paint can cover (350 ft²), which gives us:

144 ft² ÷ 350 ft²/gallon = 0.4114285714 gallons

We then round this number to two significant figures, which gives us 0.41 gallons.
