What has the greater density a cube of water measuring 1cmX1cmX1cm and having a mass of 1g or a block of plastic measuring 2cmX3cmX1cm with a mass of 4g?
Density = Mass/Volume. For water: 1/(1*1*1) = 1/1 = 1 g/cm3 For plastic: 4/(2*3*1) = 4/6 =2/3 g/cm3. So the water has the greater density.
What is the formula for finding the volume of a copper?
If you refer to a copper coin, simply place it in a measuring glass of water and work out the difference between the start and final volumes; that is the volume of the coin.
What is the advantage of measuring volume rather than length of tumours?
Think of a plastic bag filled with water. It makes more sense to describe the amount of water within the bag by it's volume vice the bag's dimensions.
Explain two ways to find the volume of a plastic cube?
Measure the length of the edge of the cube and multiply this by itself 3 times.Fill a measuring jug with enough water to cover the cube. Measure the level of water. Immerse the cube in the water in jug and measure the level of the water. The difference in level is the volume of the cube.
How do you calculate the volume of irregular solids Describe please An irregular solid is like a toy car so how would you measure the volume of that Dont understand need help click on and find out?
The volumes of small irregular solids are usually easily measured by measuring the volume of fluid displaced when they are immersed in a liquid. For example: You would have to put the object in a measuring glass with water in it. (~1/3 filled) Put the object in it and then get the number from the measuring glass (beaker etc. mostly beaker) and that is how you measure a irregular solid!
