Ablock of foam has a mass of 10 g, a volume of 60 cm3, and a length of 30 cm. what is the density of the foam? (if necessary, round your answer to three decimal places.)

The density of the foam is .

Given the following data:

Mass of block of foam = 55.0 gramsVolume of foam = 60 Length of foam = 30 cm.

To find the density of the foam;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, the density of a substance is given by the formula;

Density =

Therefore, the density of the foam is .

The density is

(Mass)/(volume)

= 10/60 = 1/6 g/cm^3 . (1.667)

If you already know the volume, then the length doesn't matter.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
