About 7.5 gallons of water fill up 1 cubic foot of space. How many gallons of water will fill a goldfish pool.

7.5, if it's a 1-ft^3 pool.

To determine the number of gallons of water that will fill a goldfish pool, you need to know the size of the pool. Specifically, you need to know the volume of the pool in cubic feet. Once you have that information, you can multiply the volume in cubic feet by the conversion factor (7.5 gallons/cubic foot) to get the number of gallons.

To calculate the volume of the goldfish pool, you will need to know its dimensions. Let's assume the pool is rectangular, with length, width, and depth measured in feet.

To calculate the volume, use the formula:

Volume (cubic feet) = Length (feet) x Width (feet) x Depth (feet)

Once you have the volume in cubic feet, you can calculate the number of gallons using the conversion factor of 7.5 gallons/cubic foot.

Let's say the goldfish pool measures 10 feet in length, 5 feet in width, and 3 feet in depth:

Volume = 10 ft x 5 ft x 3 ft = 150 cubic feet

To find the number of gallons:

Number of gallons = Volume (cubic feet) x Conversion factor (gallons/cubic foot)
= 150 ft³ x 7.5 gallons/ft³

So, the goldfish pool would require:

Number of gallons = 1125 gallons

Therefore, a goldfish pool with a volume of 150 cubic feet would require approximately 1125 gallons of water.
