INTRODUCTION
In mathematics, solid geometry was the traditional name for
the geometry of three-dimensional Euclidean space — for
practical purposes the kind of space we live in. It was
developed following the development of plane geometry.
Stereometry deals with the measurements of volumes of
various solid figures including cylinder, circular cone, truncated
cone, sphere, and prisms.
Sphere
Sphere is an object of perfect circular geometry and the dimensions of
the space it resembles a round ball and our Earth. As bulatandalam
geometric context, it is a two-dimensional. The sphere is the set of all
points the same distance r from a given point in space. The distance r is
the radius of the sphere, and a given point is the center of the sphere. The
maximum straight distance through the sphere through the center and
thus twice the radius, it is the diameter.
The formula for calculating the surface area of ​a sphere is:
Cube
In geometry, the cue is a three-dimensional solid object surrounded by six
square faces, facets or sides, with three meeting at each vertex. The cube
has six terms and is one of the five Platonic solids. The cube is two to
eight terms. It has a cubic or octahedral symmetry.
The formula for calculating the surface area of ​the cube is:
Cuboid
In geometry, a cuboid is a convex polyhedron is surrounded by six
rectangular surface, a polyhedral graph is similar to a cube. HOWEVER
some mathematical literature refers to any polyhedron as a cuboid. Other
sources use the "cuboid" to refer to this type of design in which every
face is a rectangle. This type of more stringent than the cuboid is also
known as a rectangular cuboid, right cuboid, rectangular box, rectangular
hexahedron, rectangular prism, or rectangular parallelepiped.
The formula for calculating the surface area of ​the cuboid: 2AB +2ac +2bc
Cone
Cone is a three-dimensional geometry formed from a flat base (usually
round) to a point called the apex.
More precisely, it is a solid figure is surrounded by a plane base and the
surface (called the lateral surface) formed by the locus of all straight line
segments joining the apex to the perimeter of the base, as there are a
circular cross section. The term "cone" sometimes refers just to the
surface of a solid figure, or just to the lateral surface.
Cylinder
A cylinder is one of the most basic form of curvilinear geometry, the
surface formed by the points at a fixed distance from a given line
segment, the axis of the cylinder. Solid surface and is surrounded by two
planes perpendicular to the axis is also called a cylinder. The surface area
and volume of the cylinder have been known since the time of depth.
The formula for calculating the volume of a cylinder: V = πr2h
Prism
In geometry, a prism is a polyhedron with a polygonal base "n" bias, a
translated copy (not in the same plane as the first), and n other faces
(necessarily all parallelograms) joining the same two bases. All sections
parallel to the base faces are the same. Prisms are named for their base,
so a prism with a pentagonal site called pentagonal prism. Prism is a
subclass of prismatoids.
