How do you work out the volume in maths?

Answer 1

The amount of space occupied by an object is called it's volume. Volume can be used to measure the amount of space occupied by solids, liquids or gases. Solids are relativly easy for cubiods V=l x w x h and for other regular shapes similar calculations exist. For irregular solids displacment can be used, the amount of water displaced by the solid is equal to it's volume. Liquids can placed into measuring vessles, the vessles are solids usually of regular shape with a known space inside them, an example being a measuring cylinder. Gases can be compressed to take up less volume so volume measurements are always quoted with a pressure and temperature. Gasses are measured in a similar way to liquids however the vessles used must be gas tight, an example being a gas syringe. Because the object is measured in 3 dimensions cubic units are used for measuremants eg. cm3, m3. As most substances expand when heated so measurements of volume must take into consideration the temperature at which the measurment was taken. Air pressure may also alter the volume of a substance. It is usual to quote volume measurements for standard temperature and pressure.

The volume of sound is measured in decibles(dB) with a dB meter.

just use LxWxH (lengthxwidthxheight) or if it can fit in a beacker use water displacement

Answer 2

there, what a very interesting question, i am professor Allan Shearer and i will answer your question..........

I am guessing you are looking for the formulae.

Well each 3D shape has its own volume formulae.

For Example - A cube has one length of 20cm

As you know a cubes dimensions are all the same so all the lengths are the same

here is the formulae for that sum......

Volume = length x breadth x height

Volume = 20 x 20 x 20

Volume = 8000cm3

Where as.......if we had a cylinder with a diameter of 20cm and a height of 40cm

the formulae would be.............

Volume = pi x r2 x h

Volume = 3.14 x 10 x 10 x 40

Volume = 12560cm3

As you can probably see each shape has a different formulae....... for more formuales just contact professor Allan!

Answer 3

Here is an example. 3x3x3=27+27=54.

54 is the answer.

Answer 4

To calculate volume you take the length, width, and the height and multiply them or just take the base and multiply that by the height.

Answer 5

Volume of a cuboid: length x width x height

for cube: length3

for cylinder: (pi)r2 x height

Answer 6

What do you need the volume of? .... typically width x height x length ..... gazillions of formulas available for various other things (pyramids, cones, spheres, Rosie O'Donnell, etc.)

Answer 7

The formula for volume is Length x Width x Height.

Answer 8

You times the legth by width by height and your answer will be .........cm3

Answer 9

listen to my answer and I can help you don't read that whole thing. just use lenghxwidthxhight it's that simple bye

Answer 10

You can solve volume like this v=l*w*h
