The Pyramid
1. Plane Figures- A flat, closed figure that is in a plane- A plane figure can be made of straight lines, curved lines, or both straight and curved lines.2. Solid Figures- The figures which occupy space are called solids.- Solids are three dimensional figures i.e., they have length, breadth & height.- There are two important facts related to solids-a. Every solid has a surface area. Some solids have plane surfaces, others have curved surfaces.b. Every solid has a 'bulk' & its bulk occupies some space.3. Surface area-It is the sum of areas of all visible (exposed) surfaces of a solid.4. Volume-It is the three dimensional space occupied by a solid, liquid or gas.5. Lateral surface area - is the sum of the surface areas of all its faces excluding the base.6. Total surface area - is the sum of the surface areas of all its faces including the base.
Solid figures exist in three dimensions: length, width, and height. These three dimensions allow for the representation of volume and the physical space that solid objects occupy. In contrast, two-dimensional figures only have length and width, while one-dimensional figures have only length.
It is called a polyhedron.
An equilateral parallelopiped, each of whose face is a rhombus.
There are no Platonic solids with hexagonal faces because of the geometric constraints related to the angles of regular polygons. A Platonic solid is defined as a three-dimensional shape with identical faces that are regular polygons, and the angles of hexagons do not allow for a convex arrangement that meets the required conditions for a solid. Specifically, the internal angles of a hexagon (120 degrees) are too large to fit together at a vertex in three-dimensional space without overlapping or creating a non-convex shape. Thus, Platonic solids can only be formed from triangles, squares, and pentagons.

The volume of a regular solid is the total amount of space enclosed by its boundaries. It is typically calculated by multiplying the area of the base by the height of the solid. Common regular solids include cubes, rectangular prisms, cylinders, pyramids, and cones.
There are infinitely many figures and so infinitely many formula and therefore it is impossible to give ALL of them.
Geometry dealing with 3-dimensional figures is called solid geometry. It involves studying shapes such as cubes, spheres, cylinders, and pyramids in three-dimensional space. Solid geometry includes concepts such as volume, surface area, and properties of these 3D figures.
A __________ is a space figure in which all faces are polygons.
A heptagon is a space figure with 7 faces
Volume of a solid helps us understand the amount of space it occupy's internally. Surface area of a solid helps us know what is the area of a given face/faces of a solid.
There are different kinds of space figures. The names of these space figures are rectangular prisms, cubes, pyramids, and cylinder.
A cylinder and a cone. If you look up 'space figure' in images you should get the idea.
