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 = 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?
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
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).

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.
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.
Density = Mass/Volume

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?
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.
If its a cuboid, volume = length * breadth * height .
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
The volume of a block of wood can be calculated by multiplying its length, width, and height. The formula for volume is V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height of the block.
The density of the block of wood is 0.6 g/cm^3. (Density = mass/volume)
The equation for the density of an object with known mass m and volume V is D=m/V.You are given the mass to be 750g.To figure out the volume of the block of wood, simply multipy all of the dimensions. The volume of a right prism (e.g. a block of wood) is V=length*width*height, so the volume for the block of wood is 12cm*8cm*9cm=864cm3.Now you know both your mass and your volume, so you can calculate the density:D=m/VD=(750g) / (864cm3)D is roughly equal to 0.86806g/cm3.
