Which is heavier a 1cm cubed block of iron or a 1cm cubed block of wood?
Answer: That probably would depend on the type of wood (e.g. ironwood vs balsa.?Answer: No wood is as heavy as iron. Iron would be heavier. Iron has a density of about 8 gram per cubic centimeter; would is usually lighter than water (density less than 1), but some woods are a little heavier than water.
How do you calculate volume of a wood block?
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.
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 part of the block of wood remains immersed in water of density 1000kg per cm cube when the block of wood placed in water has density 700 Kg per m cube?
-- 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.
What is the density of a piece of wood that weighs 62 grams and displaces 0.525 l of water?
This is clearly a piece of wood that is forcibly submerged since its density would require it to float. So the volume of displaced water should be equal to the volume of the whole piece of wood. Then, density = mass/volume = 62/0.525 g/L = 62/525 g/ml = 0.12 g/ml which is a lot less dense than balsa (0.16 g/ml)!
