Lateral Surface Area of an Equilateral Triangular Prism 'h' = Height of the equilateral triangular prism.'a' = Side length of the equilateral triangle.Total surface area of an equilateral prism = (√3a 2/2) + 3(a × h) When 'a' is the side length of the equilateral triangle and 'h' is the height of the equilateral triangular prism, the surface area of the three rectangular faces is 3(a × h) whereas the total area of the two equilateral triangular faces is 2 × (√3a 2/4). The formulas for LSA and TSA are given as: Total Surface Area of an Equilateral Triangular Prism The formula for the surface area of an equilateral triangular prism is calculated by adding up the area of all rectangular and triangular faces of a prism. Pyramid is a shape having base and straight lines that joins all vertices of a base at a point called apex.Surface Area of an Equilateral Triangular Prism Formula H is the height of the rectangular prism Pyramid Surface Area Formula Surface Area of Rectangular Prism Formula:.Get the formula to calculate the surface area and volume of a rectangular prism here: V is cylinder volume Rectangular Prism Surface Area Formula L is the lateral surface area of cylinder Calculate the top surface area of a cylinder:.Its formula to find the surface area is mentioned here. Two straight and parallel lines joins those circles. A = L + B = πrs + πr² = πr(s + r) = πr(r + √(r² + h²))Ĭircular cylinder is having two circles of equal radii one on the bottom one is at the top.The formula to calculate the total surface area, lateral surface area, and base surface area of a cone are given here: Its formulas are here.ĭ is the diameter of a sphere Cone Surface Area Formula The distance from centre and the point on the surface of a sphere is called radius. To find the surface area of a sphere, all you need is wither radius or diameter of the sphere. The formula to calculate the surface area of a cube is mentioned here:Ī is the length of side of a cube Sphere Surface Area Formula Each face is a square having equal side length. Surface Area of Hemisphere formula is A = 3πr²Ĭube is a three dimensional figure which is having 6 faces. Surface Area of a Canonical Frustum formula is A = π Surface Area of Capsule formula is A = 2πr(2r + a) Surface Area of Triangular Prism formula is A = 0.5 * √((a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c)) + h * (a + b + c) Surface Area of a Pyramid formula is A = l * √(l² + 4 * h²) + l² ![]() Surface Area of a Rectangular Prism (Box) formula is A = 2(ab + bc + ac) ![]() ![]() Surface Area of Cylinder formula is A = 2πr² + 2πrh ![]() Surface Area of a Cone formula is A = πr² + πr√(r² + h²) Surface Area of a Sphere formula is A = 4πr² Get the useful formulae and use them to find the surface area. The simple and universal formulas to find the surface area of a 3D shape are mentioned below. The SI unit of surface area is square metre (m²). Generally, surface area is defined for only three dimensional shapes/ objects. It is the sum of the areas of all surfaces of an 3D shaped object. Surface area of an object is defined as the total area region that the surface of the object covers.
