Length times width times height (lwh) is a way to figure out volume. If you try to do it with water displacement, the wood will adorn the water and ruin the calculations.
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.
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).
40 cubic meters
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

Density of wood = mass/volume
If its a cuboid, volume = length * breadth * height .
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
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.
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).
IF you knew the volume of the block and the density of the material it was made of you could calculate it mass (mass = density * volume) but it is normal to measure the mass of something using a mass balance.
no clue please help
Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.
Since, this is a cubical block, It can be length * breadth* height..
