Two dimensional shapes have only surface area such as polygons whereas three dimensional shapes have surface area and volume such as polyhedrons.
To define the energy or diameter parameters between two different objects, such as two types of atoms
true
Geometric mean of 2 and 12 is 4.898979485566356. Look at link: "Calculation of the geometric mean of two numbers".
No, the geometric mean is not the same as the mean of two numbers.
A couple of general observations: All shapes are geometric shapes. They may not be regular but they are still geometric. But, at a sufficiently detailed level, none of them will be geometric because all geometric shapes are ideals. A sphere, in nature is likely to be rough - at the molecular level - and so not precisely spherical. Subject to those two comments, how about: Stars (including the sun): spheres. Table salt (NaCl) crystal: cube Honeycomb : hexagonal based prism Carbon tetrachloride or methanr molecules: tetrahedra.
Triangle Plane Square
No. Idealised objects have 0 or 1 dimensions. Day to day objects have 2 or 3 dimensions. More exotic objects have 4 or more integer dimensions and fractals have fractional dimensions.

No.
It is not possible if the two geometric figures are finite.
A cylinder is a geometric solid with two circular bases.

No, the geometric mean is not the same as the mean of two numbers.
Volume mass area Latest correction: Of these, only volume is correct. Area is not space, and mass has nothing to do with occupied space. Two objects of different volume can have identical masses, and two objects of different mass can have the same volume. The only true statement that can be made between the two is that all objects with a measurable bounded volume have mass. That is why the only possible answer is Volume
