Density of wood = mass/volume
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/cmÂ³, then compare this to 1 g/cmÂ³.
since D=m/v... then the density of the block of wood would be mass / volume..... mass in grams divided by volume in ml.
If its a cuboid, volume = length * breadth * height .
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).
The volume is more dence
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.
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.
Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.
The units for density are incorrect. If the density of a block of wood is 0.5 g/cm3 then the volume of a 27 g block would be 27/0.5 cm3 = 54 cm3
Density = Mass/Volume
2cm, 4cm, 6cm
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
Since, this is a cubical block, It can be length * breadth* height..
no clue please help
Divide the mass by the volume to get the density.
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
40 cubic meters
Multiply the height, width and breadth: height x width x breadth = volume of a block
volume,weight and mass
Volume cannot be measured in centimetres and so the question makes no sense.
The blocks are of volume 1, 10, 100, 1000 cubic units.
This block of wood has a density of 0.6 g/cm3
-- 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.
