## What are the characteristics of a sphere?

In geometry, a sphere is a solid that has a completely round shape defined in three-dimensional space. Mathematically, the sphere is defined as the set of points that are located at a constant distance from a fixed point in three-dimensional space. This constant...

## Surface Area of a Sphere – Formulas and Examples

The surface area of a sphere is defined as the region covered by its outer surface in three-dimensional space. A sphere is a three-dimensional figure with a round shape, similar to a circle. The surface area of the spheres is calculated using the length of their...

## Volume of a Sphere – Formulas and Examples

The volume of a sphere is equal to the space occupied by the sphere in all three dimensions. The volume of a sphere depends on its radius since, if we take the cross-section of the sphere, we have a circle. Therefore, we have to use the length of the radius to...

## What are the characteristics of a pentagonal prism?

The pentagonal prism is a three-dimensional figure formed by two pentagonal bases. The pentagonal bases are congruent and parallel to each other. These bases are connected by five rectangular side faces. These prisms are characterized by having a total of 7 faces, 10...

## Faces, Vertices and Edges in a Pentagonal Prism

The pentagonal prism is a prism that has two parallel pentagonal bases and five rectangular side faces. These prisms are also considered as heptahedra. These three-dimensional figures have a total of 7 faces, 10 vertices, and 15 edges. Each of the pentagonal faces has...
