Can You Change The Volume Of A Solid By Changing It's Shape? What is the relationship between density, volume, and mass?

No.
You would need to alter its density in order to increase or decrease its volume, neither action would effect its total mass.
Taking the same mass object and stretching and warping it will not alter its total volume as long as its density remains constant.
Increasing external pressure acting on the object will cause it to shrink in volume and become denser. Example, a cinder block dropped into the Atlantic ocean would become smaller in size as it travelled to the sea floor, but its mass would remain the same, i.e. zero weight gain, but its volume would decrease and, as a result, its density increase. Same amount of material , just packed into a tighter area.
The opposite happens when a weather balloon rises. Lifting gas within the cell has a constant mass (gas weight) but the balloon size, and thus volume, increases as the external air pressure acting against the balloon wall decreases, allowing the trapped lifting gas to expand and occupy a greater area.
Not ripped from the net either. Just from my mad head. Maybe I should teach kids science...

Altering density doesn't necessarily change the volume. There are things in the universe that do not change shape if you add density but most do. To Author of thread: The relationship between the three are... Density = Mass/Volume

There are a lot of examples. Pressure and temperature can realistically effect it mainly. White dwarf stars that die, they ball up into pressurized volume. They keep adding mass from the elements that were within it. Therefore it's increasing it's mass and density, but keeping the volume the same. The air in our weather is constantly changing density, very little mind you, but enough to say it's changing. It's changing based mainly on temperature. Also similar things like air with weather are wood. There are different types of wood, but they have different densities. The density of gold changes , again very small, but enough to say it changes. The density within one of Jupiter's layers, metallic hydrogen layer. (highly pressurized hydrogen that acts like spinning metal) That layer adds in hydrogen and loses it constantly, so that it can use convection of heating to heat the planet. Changing mass, volume is constant ( mainly due to pressure), density is constantly altering. Realistically I am right. Temperature and pressure are not going to be constantly contained. However if you were to take a hypothetical cube of whatever, say H20. If the temperature, pressure, and no addition anything was added in, then your correct. The density would only Change based on the ratio from mass to volume.

To mr. Ducky :
If you were to hypothetically take a cube of liquid H20 and freeze it. At first it would turn to ice solid state. Well it's possible that you can change shape and volume. There is a small area of temperature range where H20 expands in ice form ( around freezing) then as it gets colder it contracts. It is keeping same density this way because H20 is still H20, there is no chemical reaction taking place. Therefore it can happen. It is even somewhat realistic that it can happen too. There shape of water is smaller (or larger) and is the volume.
He didn't ask about the state of a material/element he asked about shape. Their different.

Solids and Liquids aren't compressible. In the non quantum world, you need a contained system with pressure/temperature changes to change density while not effecting volume. In a conventional sense, the 'empty space' in some solutions and lattice structures is ignored like in aerogels and magnetorheological fluids (found in the dampers of some exotic cars; Ferrari, Porsche, Corvette, Audi...)

Atleast I know how to use simpler words, English please?

That WAS the simple version I think you'll find
