A current US one-cent coin (penny) is 19.05 mm in diameter and 1.55 mm thick.
This is about 0.442 cubic centimeters (441.8 mm3) or 0.027 cubic inches.
The UK British penny (one new pence, steel) is 20.32 mm in diameter and 1.65 mm thick.
This is about 0.535 cubic centimeters or 0.033 cubic inches.

The volume is calculated as V = h x (pi)r2 = Height times (Pi times radius squared)
The penny is 19.05 mm in diameter and is 1.55 mm thick.
(The radius is 9.525 mm)
1.55 mm x (3.14159265 x 9.525 mm x 9.525 mm)
is about 441.78 cubic mm
The volume is 2.5439333 cm ³.
It has 0.35cm3
To find the density of a penny, you would measure its mass using a scale, then measure its volume by water displacement or using a caliper to measure its dimensions. Divide the mass by the volume to calculate the density of the penny.
To find the volume of a penny, you can use the formula for the volume of a cylinder, which is V = π * r^2 * h, where r is the radius of the penny and h is the thickness. The radius of a penny is approximately 0.75 cm, and the thickness is around 0.0598 cm, so you can plug these values into the formula to calculate the volume.

The current British Penny (1992 to present) is - 20.3mm in diameter (radius = 10.15mm) and is 1.65mm thick (height). Volume = Height x Pi (Radius x Radius) Volume = 1.65 x 3.14 (10.15 x 10.15) Therefore the volume is a smidgeon greater than 534 cubic mm.
You can get a stack of pennies, measure the height of the stack and then divide by the number of pennies. You can also get the thickness by treating the penny as a cylinder, calculating the area of the face of the penny, then putting a whole lot of them in water, measuring the change of volume to get the total volume of all pennies, then divide by the number of pennies and divide again by the area of the penny to get the thickness.
A penny will not float in water, mainly because it is denser than water. When the penny is placed in water, it displaces a volume of water equal to its own volume. Since the penny weighs more than the water it displaces, it will sink.So, in order for the penny to float, you must find a liquid that is denser than solid copper -- or whatever metal or alloy a penny is made of. Mercury -- which is a liquid at room temperature -- is denser than copper. Hence, a penny will float in mercury.Possibly surface tension may allow it to float.
To determine how many pennies will fit in a 2-pound coffee can, we need to know the volume of the can and the volume of a penny. A standard penny has a volume of approximately 0.36 cubic centimeters. Assuming the coffee can is cylindrical with a diameter of 6 inches and a height of 7 inches, its volume would be around 442 cubic inches. Converting this to cubic centimeters, we get approximately 7245 cubic centimeters. Dividing the volume of the can by the volume of a penny gives us an estimate of around 20,125 pennies that can fit in a 2-pound coffee can.

To calculate the number of pennies needed to fill a 7-gallon jug, we need to consider the volume of a penny. A penny has a volume of approximately 0.36 cubic centimeters. One gallon is equivalent to approximately 3785 cubic centimeters. Therefore, a 7-gallon jug would have a volume of 26,495 cubic centimeters. Dividing the volume of the jug by the volume of a penny gives us approximately 73,597 pennies needed to fill a 7-gallon jug.
The density of two pennies would be greater than the density of one penny, as the mass of two pennies is double that of one penny while their volume remains the same. Therefore, the total mass is concentrated in a smaller volume, resulting in a higher density.
