For a regular object you measure the three dimensions of an object - length, width and height. After measuring each of these you then multiply them all together which leaves you with the volume of your object.
Alternately, you could use a different way of calculating volume: displacement. Put x amount of water in a container with measurement markers on the sides. Then add the object. Subtract the final measurement from the original measurement and you will have the volume of the object.
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
conclusion
density = mass/volume
Multiply the length by the width by the height.
1. Measure the dimensions of the solid. 2. Calculate the volume on this geometric base.
Volume = {pi}r2h where r = radius of base, h = height of cylinder.
height x length x width
Usually you can use one of the well-known formulae, for example the volume of a sphere, of a pyramid, etc.
To calculate the volume of an irregular object you will need a container with meaurements and water. Place the irregular object in your container and fill with water until the entire object is covered. Record volume A. Then remove the irregular object and record volume B. The volume of your irregulare object is equal to volume A minus volume B.
That depends on what the shape of the faces of each side of the polyhedron is - since a ten-sided figure does not create a regular polyhedron, it is impossible to calculate its volume based simply on this information.
Unanswerable - the stratosphere is a region, not a set distance from earth and is not regular.
