646 gallons of water are needed to fill the waterbed

How to determine the gallons of water?

The dimensions are given as:

8 ft long, 7 ft wide, and 1.5 ft tall

The volume is calculated as:

Volume = Length * Width * Height

So, we have

V = 8 * 7 * 1.5 cubic feet

Evaluate

V = 84 cubic feet

1 gallon = 0.13 cubic feet

So, we have:

V = 84/0.13 gallon

Evaluate

V = 646 gallons

Hence, 646 gallons of water are needed to fill the waterbed
