So, 72 square centimeters of the area of the toy pyramid will need to be painted.Formula and Calculation of DuPont Analysis The surface area of the square pyramid = Area of the bottom + Area of a side + Area of a side + Area of a side + Area of a side. Then, the lateral surface area of the pyramid (LSA)\(=\frac\times 4\times 7=14\) Consider a regular pyramid, which has a square base and triangular sides with a base perimeter of “p units”, a base area of “B unit square”, and a slant height of “l unit”. There are some specialized formulas to obtain the lateral surface area and total surface area for a regular pyramid. The total surface area or the TSA of a pyramid is equal to the LSA of the pyramid, in addition to the area of the base. The term used to denote the sum of the areas of the side faces of a pyramid (triangles) is the lateral surface area or LSA in the abbreviated form. Each base edge and apex form a triangle, called a lateral face. It is measured in square units like \(m^2,cm^2,in^2,ft^2\), and so on. Pyramid (geometry) In geometry, a pyramid (from Ancient Greek (purams)) 2 3 is a polyhedron formed by connecting a polygonal base and a point, called the apex. The total area occupied by all faces of a pyramid is its surface area. Its net is made up of four triangles and one square. The base of a square pyramid is a square, and the lateral faces are triangles. The diagram shown here is the net of the hexagonal pyramid. It has 7 faces, 7 vertices, and 12 edges. Its net is made up of one hexagon and six triangles. The hexagon serves as the base of a hexagonal pyramid, while triangles serve as its lateral faces. This is the net of the pentagonal pyramid. It has 6 faces, 6 vertices, and 10 edges. Its net is made up of one pentagon and five triangles. The base of a pentagonal pyramid is a pentagon, and the lateral faces are triangles. This is the net of the rectangular pyramid. Its net is made up of one rectangle and four triangles. The base of a rectangular pyramid base is a rectangle, and the lateral faces are triangles. The net of a triangular prism is as shown in the diagram. The triangular pyramid has 4 faces, 4 vertices, and 6 edges. The base of a triangular pyramid is a triangle, and the lateral faces are triangles as well. Pyramids are classified on the basis of the shape of their base (triangular, rectangle, pentagon, and hexagonal pyramids). If the base is in the shape of a non-regular polygon, the pyramid is known as a non-regular pyramid. The lateral faces are triangular in shape.Ī pyramid that has a base in the shape of a regular polygon is called a regular pyramid. A triangular pyramid, for example, has a triangle-shaped base, while a hexagonal pyramid has a hexagonal base.įace: The faces of a pyramid include the base and the outer lateral faces. The slant height is not defined in a non-regular pyramid.īase: This refers to the shape of the pyramid’s base. The slant height of a regular pyramid is the height of one of its lateral faces. Nets are useful to find the surface area of solids. Slant height: The slant height is the length of the perpendicular drawn from the apex to the base of one of the triangular side faces of a pyramid. The net pattern is different for different types of solids. Apex: A pyramid is a three-dimensional shape with a polygonal base and triangle-shaped faces on its side that meet at a point called the apex, or vertex.Īltitude: The altitude or height of the pyramid is the perpendicular distance between the apex and the center of the base. ![]()
