To determine whether Brandon needs more than one gallon of paint, we first need to calculate the area of the wall he wants to paint. The wall is 10 feet high and 12 feet wide.
Area of the wall = height × width = 10 ft × 12 ft = 120 square feet.
Brandon's paint covers 160 square feet per gallon. Since the area of the wall (120 square feet) is less than what a gallon of paint can cover (160 square feet), Brandon will have enough paint.
Therefore, the correct response is:
No, he won't need more paint. Brandon has enough paint to cover the 120-square-foot wall.
