![]() The length of the rectangular base is 10 cm, and its width is 6 cm. Then, the triangular prism’s volume will be:įigure 5 shows oblique square, rectangular and triangular prisms with their dimensions.įigure 5 – Different Types of Oblique Prisms and Illustration of their Dimensions Examples Example 1įind the volume of an oblique, rectangular prism of height 16 cm. If the base of the triangle is B and the height is H, then its base area is: A triangle is a three-sided polygon whose three angles sum to 180°. So, a rectangular prism’s volume will be:Ī triangular prism has a triangle as its base. If the length of the rectangle is L and the width is W, then its base area is given as: ![]() A rectangle is a quadrilateral having equal opposite sides. The volume of an oblique and non-oblique square prism is:Ī rectangular prism has a rectangular base. Where s is the length of the side of the square base. ![]() The Base Area of a square prism is given by: The volume of different kinds of oblique prisms is discussed below: Square PrismĪ square prism has a square as its base which has four equal sides. By knowing the base area, one can calculate the volume. Volume of Different Types of Oblique Prismsĭifferent types of prisms have different bases and hence have different base areas. This is because both have the same perpendicular height. The SI unit of volume is cubic meters.Īn oblique prism’s volume is equal to the volume of a right prism if both have the same bases. Where h is the height and B is the Area of the base of the prism. The formula for a prism’s volume is as follows: The volume is the space occupied by a solid object. It is not common practice to calculate the surface area of an oblique prism as there is no direct formula. The surface area of an oblique prism is not easy to calculate. The faces or sides of the oblique prism are parallelograms which is a four-sided polygon with parallel opposite sides.įigure 2 shows a hexagonal oblique prism with a demonstration of its bases and lateral faces.įigure 3 – Illustration of Length, Base Area and Base Perimeter of a Rectangular Prism for Surface Area Lateral FacesĪ prism’s lateral faces are the faces that are on its sides instead of its top and bottom. These bases are parallel to each other regardless the prism is right or oblique.įor example, a pentagonal prism has two pentagons as bases on each end of the prism. The two bases are the two unique sides of a prism which defines the type of prism according to its shape. The edges of a prism are parallel to each other, extending from one base to the other. It has equal cross-sections with identical bases. It is a polyhedron with flat faces, straight edges, and sharp vertices. To understand an oblique prism comprehensively, first, we need to know about the “ prism.” PrismĪ three-dimensional object with two same ends is known as a prism.
