u need the volume . if u did have the volume u would divide the mass (27g) by the volume. then add the label g/ml
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water. -- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced its entire weight in water, and floats. -- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.
Density= Volume/Mass. Therefore: (9x2x6)divided by 5.4g=Density. 108cm/5.4g=Density. 20=Density.
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.
it is the same because the molecular structure did not change when you cut the wood in half.
Density = mass/volume = 5.4g/(9*2*6) cm3 = 5.4/108 cm3 = 0.05 g/cm3. Balsa, one of the least dense woods, has a density of 0.16 g/cm3 which is more than 3 times the "density" of your wood! So have you discovered a super-light wood species?
A cube, with 3cm sides, has a volume of 3x3x3 = 27cc The weight is 27grammes. Density = weight / volume = 27g / 27cc = 1g/cc = 1000Kg/M3 A relative density of 1.0 (same as water)
Density = Mass/Volume
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.

Density of wood = mass/volume
A triple-beam balance can be used. The units could be g/ml the density of a normal wood is 0.88 but a wood block in density can be anything under 1 so it can be 0.95,0.54,etc. waters density is 1 and would can float on water so wood is anything below 1.
Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water. -- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced its entire weight in water, and floats. -- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.
A block of wood can be of different sizes; this will affect the mass, and weight, a lot. To a lesser degree, the weight of a block of wood will also depend on the density, since different types of wood have different densities.
Density = mass/volume = 27/3 = 9 grams per millilitre.
This density is 0,8 g/cm3.
depends on its size and the density of the wood.
