# Some facts#

• Stereometry is a branch of mathematics dealing with the study of three-dimensional solids and the relationships between them.
• Stereometry is the equivalent of a plane, two-dimensional geometry (sometimes called planimetry) in three-dimensional space. For this reason the term solid geometry, three-dimensional geometry or 3D geometry are used.
• Spatial shapes (equivalents of flat figures in three-dimensional space) are often called solids. Examples of typical solids are, among others:
• sphere - it is a generalization of the circle into three-dimensional space,
• cuboid - generalization of rectangle,
• cube - generalization of square,
• cone,
• cylinder,
• itd.
• The most typical solid properties are:
• lateral surface area - it is the sum of all external surfaces of the solid, e.g. in case of a cube, there are six identical walls with the same area, therefore the cube field is:
$S = 6a^2$
where:
• S - lateral surface area of the cube,
• a - the length of the cube edge, it is equal between all the edges: the width of the base, the length of the base and the height of the whole cube.
• volume - determines how much space the given solid occupies, e.g. the cube volume is:
$V = a^3$
where:
• V - cube volume,
• a - the length of the cube's edge.
• The lateral surface area is the sum of the flat figures. When measuring the total area, we always deal with square units, for example, square meters ($m^2$).
• You can find more about square units and the concept of surface area in our other calculator: Area units.
• If you want to learn more about the geometry of flat figures (2D), check out our other calculator: Math tables: geometry.
• The volume of the solid is always given in cubic units e.g. cubic decimeter ($dm^3$).
• Volume is a property unique to spatial solids. It means that it has no sense for flat, two-dimensional shapes.
• If you want to learn more about cubic units and the volume, check out our other calculator Volume (capacity) units.
