The density of maple wood is about 755.kg/m. what is the mass of a solid piece of maple that has a volume 640.cm?

I believe that the correct given values are:

density = 755 kg/m^3

volume = 640 cm^3

First let us convert volume to m^3 units.

volume = 640 cm^3 * (1 m / 100 cm)^3 = 6.4 x 10^-4 m^3

so the mass is:

mass = 755 kg/m^3 * (6.4 x 10^-4 m^3)

mass = 0.4832 kg = 483.2 g

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
