First, calculate the area of the hallway by multiplying its dimensions: 90 feet × 7 feet = 630 square feet. Since 12 fluid ounces of cleaning solution are needed per square foot, multiply the area by the solution requirement: 630 square feet × 12 fluid ounces/square foot = 7,560 fluid ounces. Therefore, 7,560 fluid ounces of cleaning solution are required to clean the hallway.
One square foot of water exerts a pressure of approximately 62.4 pounds per square foot at sea level. This is based on the weight of water, which is about 62.4 pounds per cubic foot. The pressure exerted increases with depth, following the principle that pressure is equal to the weight of the water column above the area.
