A prism is a 3-dimensional shape with two identical shapes facing each other.
A triangular prism has six vertices. The shape of the prism does not have any curve. Based on the shape of the base, prisms are regular or irregular prisms.The surface area of a prism is the sum of the area of all its faces. But if the two ends are not parallel it is not a prism.

A prism is a polyhedron for which the top and bottom faces (known as the bases) are congruent polygons, and all other faces (known as the lateral faces) are rectangles. These identical shapes are called “ bases ”. A triangular prism has five faces: the two triangular ends and three rectangular faces. The cross-section looks like a triangle hence called triangular prism. A prism has a solid shape consisting of two equal ends, flat faces or surfaces and identical cross-section across its length. A prism can not have any side which is curved thus objects like cylinder, cone or sphere are not prisms.We use cookies to give you a good experience as well as ad-measurement, not to personalise ads. They are characterized as follows:The prisms are polyhedrons or objects with multiple flat faces. In geometry, a prism is a polyhedron comprising an n-sided polygonal base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases. The cross section of a geometric shape or an object is the shape obtained by cutting it straight.
Edge. (Technically, when the sides are rectangles, the shape is known as a right prism, indicating that the lateral faces meet the sides of the base at right angles. Prism is a three-dimensional solid object in which the two ends are precisely the same shape.
A vertex (corner) is a place where two or more edges meet. The Complete K-5 Math Learning Program Built for Your ChildFind the volume of solids by multiplying the area of the base by the height of the solid. The number of edges is decided by the shapes at either end. It is also referred to as the intersection of a plane with the three-dimensional object. As the prism is a three-dimensional shape, so it has both the properties, i.e., surface area and volume.The surface area of the prism is the total area covered by the faces of the prism.For any kind of prism, the surface area can be found using the formula;The volume of the prism is defined as the product of the base area and the prism heightFor example, if you want to find the volume of a square prism, you must know the area of a square, then its volume can be calculated as follows:The volume of a square Prism = Area of square×heightThe volume of a prism = Base area × Height cubic unitsTherefore, the height of the square prism is calculated as follows:For more information on other maths-related articles, stay tuned with BYJU’S – The Learning App and also watch interactive videos to learn with ease.Wow this is a great website my daughter is learning so much about it. Vertex. Other faces of a prism are parallelograms or rectangles. It is of two types, namely;Apart from regular and irregular, the prism can be classified into two more types;Based on the shape of the bases, it is further categorised into different types, namely;The formulas are defined for the surface area and volume of the prism. The bases can be a triangle, square, rectangle or any other polygon. Prisms are named for their bases, so a prism with a pentagonal base is called a pentagonal prism. A triangular prism has nine edges. The faces of the prism are parallelograms without the bases.
All cross-sections parallel to the bases are translations of the bases. Let us see how to find the surface area and volume of a triangular prism.Surface Area = Area of base triangles + Area of side parallelogramsLength (l) = 12 cm, Height (h) = 4 cm, Base (b) = 6 cm, Side (s) = 5 cmWhen the two bases of a prism are perfectly aligned and its faces are rectangles (perpendicular to the bases) it is a right prism, else it is an oblique. Remember, that volume like area can be added.The bases can be a triangle, square, rectangle or any other polygon. Volume of a prism is the amount of space inside the prism. The number of faces on the prism is decided by the shapes at either end.
Therefore, a prism can have cubic, rectangular, pentagonal and other polygon shapes but not the circular shape.Depending upon the cross-sections, the prisms are named. The prisms are a subclass of the prismatoids. The side faces of a prism are parallelograms ( 4-sided shape with opposites sides parallel) A prism can lean to one side, making it an oblique prism, but the two ends are still parallel, and the side faces are still parallelograms!
