To find the volume of an object using the overflow can method, you first fill a container with a known volume of water. Then, you submerge the object in the water, causing the water level to rise. The increase in water level represents the volume of the object. By measuring this increase in height and knowing the initial volume of water in the container, you can calculate the volume of the object using the formula for the volume of a cylinder (V = πr^2h).

First pour water into the can until it overflows and drains. Next place an object into the overflow can, being careful not to spill. Place a beaker under the overflow can to collect the water that is displaced by the object. Record the volume in millimeters of the displaced water. This is the volume of the object.
To find the volume of an object, we use an overflow cylinder as it gives a measure of the volume of the object by displacing an equal amount of water into the beaker.
To find the volume of an irregular shape, you need to use the water displacement method. If the object can fit into a graduated cylinder, fill the cylinder with enough water to adequately cover the object, but don't put the object inside the cylinder yet. Record the amount of water in the cylinder. Carefully drop the object into the cylinder. This will cause a rise in the water in the cylinder. Record this second volume. Subtract the first volume from the second volume, and the difference is the volume of the irregular object. For larger objects, use an overflow can.
To find the volume of an irregular solid using the overflow can method, you would first fill the overflow can with water and measure the initial volume. Next, you would submerge the irregular solid in the overflow can, causing the water to overflow. Measure the new volume of water in the overflow can with the solid submerged. Finally, you would subtract the initial volume from the final volume to find the volume of the irregular solid.
The answer depends on what information you do have about the object.
The volume of a rectangle is 0. It is a 2-dimensional object and so has no volume.
