Question

A painter can paint 7.2 ft.² each minute each gallon of paint they use pin cover and 41 m² of wall. How much time does it take to use of 3 gallons of paint

Answer 1

Step-by-step explanation:

3 gal × 41 m²/gal = 123 m²

123 m² × (3.28 ft/m)² = 1323.28 ft²

1323.28 ft² × 1 min / 7.2 ft² = 183.79 min

183.79 min × 1 hr / 60 min = 3.06 hr

Rounded to two significant figures, it takes 180 minutes, or 3.1 hours.
