The number of sides a pyramid has depends on the shape of its polygonal base; for example, if the base of a pyramid is a square, it will have five sides, which are four triangular sides and one square side. A pyramid whose base is n sides has n+1 faces, n+1 vertex and 2n edges.Continue Reading
The different types of pyramids are named after the shape of their polygonal base. For example, a pyramid with an octagon shaped base will be an octagonal pyramid. When the shape of the base is not specified, it is typically assumed to be a square. A pyramid with a triangular base is generally referred to as a tetrahedron.
A pyramid whose apex is located directly above the center of the base are known as right pyramids, while the opposite is called an oblique pyramid. If the base of the pyramid is not a regular polygon, it's called an irregular pyramid; otherwise it's a regular pyramid.
The volume of all pyramids is given by (b*h)/3, where b is the base area and h is the height from the center of the base to the apex. The total surface area of any pyramid is the total sum of the surface areas of each face. Aside from the base, all the faces of a pyramid are triangles. If it is a regular pyramid, all the triangles are isosceles and congruent.Learn more about Shapes
Find the volume of a square pyramid by using the formula (1/3) x A^2 x h, where A is the measurement of one side of the square base and h is the height. You need to know the values of the base and the height of the pyramid.Full Answer >
The surface area of a rectangular pyramid is found by adding the area of the base to the combined area of the four triangular sides. The area of the base is found by multiplying length times width. The area of each triangle is found by multiplying 1/2 base times height.Full Answer >
A square pyramid, a pyramid with four triangular sides and one square side, is a figure with five faces, eight edges and five vertices. It is a kind of three-dimensional solid. The pyramids at Giza, Egypt are examples of such a figure.Full Answer >
Shapes can have an infinite number of sides, but one example with a large number of sides is the googolgon, which has 10100 sides. Other examples of shapes with a large number of sides include the chiliagon (1,000), myriagon (10,000) and megagon (1,000,000).Full Answer >
