Generally speaking, geometry is a mathematical formula of the volume of a graph composed of faces, intersection lines (intersection points of faces) and intersection points (intersection points of intersection lines or convergence points of surfaces).
Cuboid volume formula: volume = length × width × height. The volume formula of a cube is v = a.a.a = a? . The volume of the cone = the area of the bottom × the height × one third. Triangular pyramid is the most common and basic figure in three-dimensional space, just like triangle in two-dimensional space.
When calculating the volume of space aggregate, we should first consider that space aggregate is composed of those basic geometric bodies-cylinder, cone, platform and sphere.

Cubic millimeter? Hmm?
1 m3 = 1000 cubic decimeter
1 cubic decimeter = 1000 cubic centimeter
1 cm3 = 1000 cm3
1 l = 1 cubic decimeter = 1000 ml = 1000 cubic centimeter.
