Hence, the surface area of the prism is 136 square units.Įxplore Now Online Course of Class 9 Neev Fastrack 2024 and Class 10 Udaan Fastrack 2024 to enhance your Maths knowledge. Substituting the values into the formula: Solution: the surface area is calculated using the formula: Given a prism with a base area of 14 square units, a base perimeter of 18 units, and a height of 6 units. Surface Area of a Prism Solved ExamplesĮxample: Determining the Surface Area of a Prism Step 3: The calculated value represents the surface area of the prism, concluding with the unit for the surface area (typically in square units). Step 2: Insert these dimensions into the surface area formula for the prism, which is (2 × Base Area) + (Base perimeter × height). Step 1: Note Down the provided dimensions of the prism. Here’s a straightforward guide to finding the surface area of a prism: Substituting the values into the formula gives us the surface area of a triangular prism as bh + (a + b + c)H = (2A + PH). Hence, applying the surface area formula for the prism, which is (2 × Base Area) + (Base perimeter × height), considering a triangular base with an area of A = ½ bh and a perimeter of the sum of its sides (a + b + c). This prism features two triangular bases. We will compute the surface area of the triangular prism depicted below, utilizing the base “b,” the height of the prism “h,” and the length “L.” Surface area of octagonal prism = 4a2 (1 + √2) + 8aH ![]() Surface area of regular hexagonal prism = 6ah + 3√3a Surface area of hexagonal prism = 6b(a + h) Surface area of pentagonal prism = 5ab + 5bh Surface area of trapezoidal prism = h (b + d) + l (a + b + c + d) Surface area of rectangular prism = 2(lb + bh + lh) Surface area of triangular prism = bh + (s1 + s2 + b)H Surface Area of Prism = (2 × Base Area) + (Base perimeter × height) Refer to the table below to comprehend the relationship between the surface area and the various types of prisms. Prisms come in various types, each with distinct bases, leading to different formulas for determining their surface areas. The total surface area of a Prism = Lateral surface area of the prism + area of the two bases = (2 × Base Area) + Lateral surface area or (2 × Base Area) + (Base perimeter × height). Hence, the lateral surface area of a prism is calculated as the base perimeter multiplied by the height. The lateral area belongs to the vertical faces of the prism when the bases are positioned facing upwards and downwards. Let’s examine the formula for the surface area of a prism. This total surface area comprises the sum of the lateral surface area and the area of the two flat bases. The surface area of any prism is determined using a standard formula. Determining the surface area of a prism involves computing the total area encompassed by all the faces of that specific type of prism or summing the areas of all faces (or surfaces) within a three-dimensional space. The surface area of a prism represents the collective space taken up by its flat faces. Prisms, being polyhedrons, hold flat faces and no curved surfaces. It is calculated as the sum of the areas of all the faces comprising the prism. ![]() Surface Area of a Prism: The surface area of a three-dimensional prism depends on the configuration of its base.
