A material with a density of approximately 7900 kg per cubic meter is typically iron or certain types of steel. This density is characteristic of many ferrous alloys, which are widely used in construction and manufacturing due to their strength and durability. Other materials, such as some types of copper alloys, may also exhibit similar densities.
Usually such magnets are made out of iron. If that is the case, I would expect its density to be similar to that of iron (approximately 7900 kg/m3).
20% of 7900= 20% * 7900= 0.2 * 7900= 1580
To calculate 7900 percent of 8000, calculate (7900 / 100) x 8000.

There are 1000 grams in one kilogram. Therefore, 7900 grams is equal to 7900/1000 = 7.9 kilograms.
Wikianswers calculator says 7900 * 3.14 = 24806.
