Volume
Density of wood = mass/volume
To calculate the density of the block of wood, you would divide its mass (in grams) by its volume (in milliliters). The formula for density is: Density = Mass / Volume. Plug in the values for mass and volume to find the density of the block in g/mL.
you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume
If its a cuboid, volume = length * breadth * height .
To find the density, first calculate the volume of the block by multiplying the three dimensions (12cm x 8cm x 9cm = 864cm³). Then, divide the mass (75g) by the volume to find the density. So, the density of the wood block is 75g / 864cm³ ≈ 0.09 g/cm³.
The density of the block of wood is 0.6 g/cm^3. (Density = mass/volume)
A block of light balsa wood and a block of heavy teak of the same size, will also have the same volume (which is the space each block occupies).
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 graduated cylinder or volumetric flask could be used to measure the displacement of water when the wood block is submerged in it. By measuring the volume of water displaced, you can determine the volume of the wood block. A balance can then be used to measure the mass of the wood block, allowing you to calculate its density.
Since, this is a cubical block, It can be length * breadth* height..
A ruler. Measure the length, width, and height. Then multiply the three of the to get the volume. Equation: V=LxWxH V=Volume L=Length W=Width H=Heigtht x=multiply Example: A block of wood has a length of 4, a height of 2, and a width of 3. What is the volume? 4x2x3=24
