volume = mass ÷ density
= 2.5g ÷ 6.72 g/cm3
≈ 0.372 cm3
Volume = Mass/Density = 2.50/6.72 = 0.37 cubic cm.
Density = Mass/Volume = 962/350 = 2.7485 grams per cubic centimeter
Volume is a measure of size. A block of gold that is 1 centimeter on each side is, (wait for it!) 1 cubic centimeter in volume. If it is 1 inch on each site it would be 1 cubic inch in volume.
You need to know the density o f Mg D = Mass/Volume Mass = Density * volume Density= 1.74 grams per cubic centimeter Volume = 2.5 * 3.5 * 1.5 Mass = Density * volume
Divide the mass of the object by the object's volume. For example, a 20 cubic centimeter block that weighs 40 grams would have a density of 2 grams per cubic centimeter (or milliliter), or abreviated as 2g/mL
If the density of the block is less than the density of water, then the block will float. Density of water is close to 1 gram per cubic centimeter. So measure the block and calculate its volume (Length x Width x Height). Use a scale to find the block's mass. Then divide mass/volume to calculate density. If you've measured in grams and centimeters, then the units will be g/cm³, then compare this to 1 g/cm³.
Density = Mass/Volume
It is the mass of the block divided by its volume.
Density = Mass/Volume = M/(L*H*W) = 10/(58*24*20) = 10/27840 = 0.00036 grams per cm3. This is totally unlikely since even light balsa has a density of more than 0.1 g/cm3
4096 cm is not a volume, but a length. Once you know the volume, divide the mass by the volume to get the density.
Cubic centimeter.
The block's density is about 0.076 g/cm3
What is the density of a plastic block with a mass of 2.0 grams and a volume of 2.5cm3?
