Calculate the density

Calculate the density of a solid cube that measures 2.58 cm on each side and has a mass of 426 g. Answer in units of g/cm^3

To get your volume, you need the volume of the cubs. Volume = length x width x height. So, it's a cube, length=width=height. So, (2.58)(2.58)(2.58) = 17.17 cm^3 for volume.

Density = mass/volume

Your mass is 426 g, so 426/17.17 = 24.81 g/cm^3

You CAN divide kilograms by centimeters to acheive density, because density's UNITS are in kilograms per meter, or if you want, it can be in grams per centimeter.... It doesn't matter.... Densities unit is just that.

So convert kg into g
Then when solve for density you will get:

D=m/v
so... D=426g/2.58 cubed(2.58x2.58x2.58)
just type that into a calculator (following the order of operations) and there's you answer!

density = mass/volume

volume of cube = 2.58 x 2.58 x 2.58 =17.17

426/17.17 = 24.81 g/cm^3

D= m/ v... DIY

426 / 2.58^3 = 24.8g/cm^3 (1 d.p.)
