![]() Step 2: Find the volume of the prism using the formula V = B × H where "V", "B", and "H" are the volume, base area, and height of the prism.Step 1: First write the given dimensions of the prism.We can find the volume of the prism using the following steps: ![]() The volume of a prism is given as V = B × H where, "V" is the volume of the prism, "B" is the base area of the prism, and "H" is the height of the prism. The formula for the volume of a prism is obtained by taking the product of the base area and height of the prism. The unit of volume of the prism is expressed in m 3, cm 3, in 3, or ft 3. The volume of the prism depends on the base radius of the prism and the height of the prism. The amount of space occupied by a prism is referred to as the volume of a prism. Thus, the unit of volume of the prism is given as V = (square units) × (units) = cubic units.įAQs on Volume of Prism What is the Definition of the Volume of a Prism? The unit of base area is given in square units and the height of the prism is given in units. Thus, the volume of a prism can be given as V = B × H where V is the volume, B base area, and H height of the prism. Volume of octagonal prism = Area of octagon × height of the prism Volume of hexagonal prism = Area of hexagon × height of the prism Volume of pentagonal prism = Area of pentagon × height of the prism Volume of trapezoidal prism = Area of trapezoid × height of the prism Volume of rectangular prism = Area of rectangle × height of the prism Volume of square prism = Area of square × height of the prism Volume of triangular prism = Area of triangle × height of the prism Look at the table below to understand this concept better: Shape Thus, as the bases of different types of prisms are different so are the formulas to determine the volume of the prism. ![]() Let us solve some examples to understand the concept better.The formula for the volume of a prism is given by the product of the area of the base and height of the prism. Total Surface Area ( TSA) = ( b × h) + ( s 1 + s 2 + s 3) × l, here, s 1, s 2, and s 3are the base edges, h = height, l = length The formula to calculate the TSA of a triangular prism is given below: The total surface area (TSA) of a triangular prism is the sum of the lateral surface area and twice the base area. Lateral Surface Area ( LSA ) = ( s 1 + s 2 + s 3) × l, here, s 1, s 2, and s 3 are the base edges, l = length Total Surface Area The formula to calculate the total and lateral surface area of a triangular prism is given below: The lateral surface area (LSA) of a triangular prism is the sum of the surface area of all its faces except the bases. It is expressed in square units such as m 2, cm 2, mm 2, and in 2. The surface area of a triangular prism is the entire space occupied by its outermost layer (or faces). Like all other polyhedrons, we can calculate the surface area and volume of a triangular prism. So, every lateral face is parallelogram-shaped. ![]() Oblique Triangular Prism – Its lateral faces are not perpendicular to its bases.Right Triangular Prism – It has all the lateral faces perpendicular to the bases.
