Estimate the galloon of paint base on the surface area given:
A storage has an area of 100 sq. ft. , with a width dimension and wall height in 10 ft.
All walls are in same height. Windows has 90 sq. ft opening but to be filled. Door has a standard opening dimension. Calculate how many quarts of gallon needed for 2 coatings?
note: 1 gallon = 300 sq. ft
Correct Answer
D. 10
Explanation
The total surface area of the walls can be calculated by multiplying the width dimension by the wall height, which is 10 ft in this case. So, the total surface area of the walls is 100 sq. ft. The windows have a total opening area of 90 sq. ft, but they need to be filled, so we can subtract this from the total surface area of the walls. The remaining surface area that needs to be painted is 100 sq. ft - 90 sq. ft = 10 sq. ft. Since 1 gallon of paint can cover 300 sq. ft, we divide the remaining surface area by 300 to find out how many gallons are needed. 10 sq. ft / 300 sq. ft = 0.033 gallons. Since we need 2 coatings, we multiply this by 2 to get the final answer of 0.066 gallons.
