How do you calculate if a block of wood will float in water or not?
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.
What is the density of a block of wood measuring 9cmX2cmX6cm with a mass of 5.4g?
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?
How do you calculate the volume of a block?
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
How can two blocks of wood have the same volume but one is denser?
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 block of wood has a height of 10 m a length of 2 m and a width of 2 m What is the volume of the block of wood?
40 cubic meters
