The US one-cent coin is 0.750 inches in diameter and 0.061 inches thick,for a volume of 0.027 cubic inches.The UK plated-steel penny (one new pence) is 20.32 mm in diameter and 1.65 mm thick, for a volume of 0.535 cm3 or about 0.033 cubic inches.(see related question)

A penny is a unit if currency (money), thus one penny means one unit/coin of this currency (1p).
One penny is one percent of one dollar in United States currency.
The coin that is not a penny is a quarter. The other one IS a penny.
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.
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.
One old penny would by one penny lolly
One of them is not a penny but the other one is! One nickel and one penny. Trick question. The other one is a penny.
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 4.42 x 10-7 cubic meters.The 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 5.35 × 10-7 cubic meters.(see related question below)
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.
the volume of a cylinder. V=pi*r2*h. Volume equals pi times the radius of the penny squared times the heighth. now if you want to get into the really serious micrometric volume taking into account all the valleys and ridges of the surface details on the obverse and reverse faces, well then GOOD LUCK and I will stay as far away from that nightmare of weeks and months of measurements as I can possibly get.
