Calculate the density of a rectangular piece of wood from the following dаta:

Length: 25 cm. Width: 10 cm. Height: 4 cm. Mass: 15 g

a.

0.015 g/cm3

c.

0.015 g/ml

b.

10.015 g/ml

d.

None of the above

Density is the measure of how a certain volume weighs. So to get the density, we divide the weight by the volume of a certain material. This probem already gave us the weight which is equal to 15 grams. Our next task is to get the volume of the material. This problem gave us the dimensions of the object. Hence the volume is just 1000cm^3 (note cm^3 = ml) The density is then 0.015 g/cm^3.
