The surface area of a rectangular pyramid is calculated by adding the areas of all the faces of the pyramid. In this type of pyramids, we have one rectangular face and four triangular faces. The opposite triangular faces have the same area. In total, we need three...

The volume of a rectangular pyramid is defined as the three-dimensional space occupied by this figure. We can calculate the value of this volume by multiplying the area of the base by the height of the pyramid and dividing by three. This means that we need three...

A triangular pyramid is a three-dimensional figure, in which all its faces are triangles. These pyramids are characterized by having a triangular base and three lateral triangular faces. Triangular pyramids have 4 faces, 6 edges, and 4 vertices. Three faces...

The surface area of a triangular pyramid is equal to the sum of the areas of all the faces of the pyramid. In this type of pyramids, all the faces are triangular, so we have to use the formula for the area of a triangle to get a formula for the surface area. Here, we...

The volume of a hexagonal prism is the total space occupied by the prism in three-dimensional space. We can calculate the volume of these prisms by multiplying the area of the base by the height of the prism. The area of the base is equal to the area of a hexagon. The...

The diameter of a sphere is equal to the line segment connecting two ends of the sphere and passing through the center. Diameter is an important measure of the sphere since, similar to the radius, we can also use the diameter to calculate the volume and surface area...
