You measure the density of any substance in units of [mass] / [volume], for example, grams per cubic cm., kg. per cubic liter, or (to use SI units) kg. per cubic meter.
180 grams / 30 cm3 = 6 g/cm3.
The density of poplar, balsam wood is 0.331 grams/cm3. The density of poplar, yellow wood is 0.427 grams/cm3.
The mass is 0.72 grams.
density = mass ÷ volume = 600 g ÷ 30 cm3 = 20 g/cm3
120/200 = 3/5 = 0.6 g/cm3

Centimeters are not the right units to use for volume. Although, if it is centimeters cubed(cm^3) then it would be: 33.3g / 6.02cm^3 = 5.53156 g/cm^3
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 = 60/20 = 3grams/ccNote:The Physics and the math in this answer are bullet-proof, but there is no woodon Earth with even half that density. I suspect your block has a concrete center.
No. It doesn't matter how heavy a block of wood is, it depends on the density of the wood. Generally wood floats as the density of wood is lighter than the density of the water, so it would float.
The density of balsa wood typically ranges from 80 to 160 grams per cubic centimeter.
The density of the wood block is calculated by dividing the mass (5 grams) by the volume (20 cm^3). Therefore, the density of the wood block is 0.25 g/cm^3.
