Geometry, or algebra (integration).
A tape measure or ruler, A book on solid geometry, A calculator or computer.
you can find the volume in a solid by taking the substance and putting it into a cilinder and measureing the change in inches.
Use a digital mass scale or a triple-beam-balance scale to find the mass of a regular solid.
The formula of volume
a base of a right solid whose height is 6 centementers shown. Find the volume. area is 28 cm and the height is 7cm
mass over volume
The water displacement method is typically used to find the volume of an irregular solid. The object is submerged in a known amount of water, and the increase in water volume is measured. This increase in volume is equal to the volume of the irregular solid.

You measure its mass and volume and then density = mass/volume.
Mass
If the solid is a regular shape, such as a cylinder or sphere, you can find the appropriate dimensions and use formulas to find the result. If it is of a irregular size, I doubt if there is another method (even if there is, displacement of water would most likely be the simplest method)
Liquid displacement
V= Base Area * Height

you cut it into regular solids then figure out those then add them together
The volume of the similar solid would be 16M squared.
You multiply base by height times length or depth and you got yourself a volume.
