A swimming pool 35 ft. long and 20 ft. wide is filled to an average depth of 5ft.
How many gallons of water does the pool contain if a cubic foot holds 7 gallons?
35 * 20 * 5 * 7 = ?
To find the number of gallons of water in the pool, we need to calculate the volume of the pool first. The volume of a rectangular prism (such as the swimming pool) can be found by multiplying its length, width, and depth.
Given:
Length of the pool = 35 ft
Width of the pool = 20 ft
Average depth = 5 ft
To find the volume:
Volume = Length × Width × Depth
Volume = 35 ft × 20 ft × 5 ft
Volume = 3500 ft³
Now, we know that each cubic foot holds 7 gallons of water. To find the number of gallons, we need to multiply the volume of the pool by the conversion factor.
Number of gallons = Volume × Conversion factor
Number of gallons = 3500 ft³ × 7 gallons/ft³
Number of gallons = 24,500 gallons
Therefore, the pool contains 24,500 gallons of water.
