A bathtub can hold about 2 cubic meters of water, we'll say it is half full because no one ever completely fills a tub. A penny is 19mm by 1.27mm thick and i will use a square formation because it is easy to calculate and pennies will not naturally align in the most efficient triangular formation. So each penny takes up about 458.5mm cubed. There are a billion cubic millimeters in a cubic meter so divide a billion by 458.5 and you get 2.18x10^6 or $22,000 in pennies. Pennies before 1982 weighed 3.1 grams and a 2.5 grams afterward. I have 70 pennies and and 18 are pre 1982 so the average penny today is about 2.65 grams. Take that times 2.18x10^6 and you get 5,786,342 grams, 5,786.342 kilograms, or 12,729 pounds. A solid cubic meter of copper weighs 8,960 kilograms.

Archimedis was so deep into thought that he filled up his bathtub full before he climbed in. When he climbed into the bathtub, the water spilled out of it and on the bathroom floor. He then realized that his mass caused the water to spill and if he collected the water and measured its mass it would be the same as his mass. He ran out of his house without wearing anything saying EUREKA!

Because we take the water's space so it needs to rise. It was discovered by Aristotle when he fulled his bath full of water and it overflowed.

The mass of a penny is approximately 2.5 grams. To make 5 grams, you would need 2 pennies, as 2.5 grams x 2 = 5 grams.
The new pennies have less mass because they are now mostly made of zinc with a thin copper coating, while the old pennies were made of bronze. The change was made to reduce production costs and to make the coins more affordable to produce.
The mass will be 11 * 2.5 = 27.5 grams.
