How much water it can hold?

To determine how much water a container can hold, you need to know its dimensions (length, width, and height for rectangular containers, or radius and height for cylindrical ones) and use the appropriate volume formula. For example, the volume of a rectangular container is calculated by multiplying its length, width, and height, while for a cylinder, it's π times the radius squared times the height. Once you have the volume in cubic units, you can convert it to liters or gallons if needed.
