Answers will be the same whether in feet, ft 2, ft 3, or meters, m 2, m 3, or any other unit measure. Units: Units are shown for convenience but do not affect calculations. Height is calculated from known volume or lateral surface area. Surface area calculations include top, bottom, lateral sides and total surface area. This calculator finds the volume, surface area and height of a triangular prism. It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles. Step 4: Find the total surface area of the pyramid using the formula (1/2) Pl + B.B = side length b = bottom triangle base bĪ lat = lateral surface area = all rectangular sidesĪ bot = bottom surface area = bottom triangleĪ triangular prism is a geometric solid shape with a triangle as its base.Step 1: Find 'l' using the Pythagoras theorem, l 2 = (a/2) 2 + h 2.Let us understand this using the following steps. Now, if only 'a' and 'h' are given and we need to find the surface area, then we need to find the slant height first. Let us consider a pyramid whose base is a regular polygon of side length 'a', the slant height of the pyramid is 'l' and its altitude is 'h'. The surface area of a pyramid can be calculated if the altitude is given. How to Find the Surface Area of Pyramid With Height (or Altitude)? The base area can be found by applying the formulas of the area of a polygon. Consider a pyramid whose slant height is 'l', the base perimeter is 'P', and the base area is 'B'. Its total surface area can be calculated using the formula, (1/2) Pl + B. The formula which is used to find the surface area of a pyramid can be calculated using the slant height. How to Find Surface Area of Pyramid With Slant Height? Where 'B' is the base area, 'l' is the slant height, and 'P' is the base perimeter. The formula that is used to find these two areas is given below. There are two types of surface areas of a pyramid, one is the total surface area and the other is the lateral surface area. What is the Formula for Surface Area of Pyramid? The lateral surface area of a pyramid is calculated using the formula LSA = (1/2) Pl, where 'P' is the perimeter of the base and 'l' is the slant height. The lateral surface area of a pyramid is the sum of the areas of all its side faces (which are triangles). What is the Lateral Surface Area of Pyramid? ![]() The total surface area of a pyramid whose base perimeter is 'P', the base area is 'B', and slant height is 'l' is calculated using the formula TSA = (1/2) Pl + B. The total surface area of a pyramid is obtained by adding the area of all its faces (both the base and the side faces). What is the Total Surface Area of Pyramid? There are two types of surface areas - the Total Surface Area (TSA), which is the sum of the areas of all the faces, and the other is the Lateral Surface Area (LSA), which is the sum of the areas of the side faces. The surface area of a pyramid is defined as the sum of the areas of all its faces. Difference Between Area and Surface AreaįAQs on Surface Area of Pyramid What is the Definition of Surface Area of Pyramid?.Now that we have the slant height, the base length, and the height, we can find the surface area of the pyramid using the formula, Total surface area of pyramid (TSA) = LSA + base area = (1/2) Pl + B So, we can calculate the slant height using the formula, l 2 = h 2 + (a/2) 2. Hence, we can apply the Pythagoras theorem and find out the slant height if the altitude and base length is given. Observe the figure given below which shows that the triangle formed by half the side length of the base (a/2), the slant height (l), and the altitude (h) is a right-angled triangle. ![]() The surface area of a pyramid can be calculated if its altitude is given. Using these two formulas, we can derive the surface area formulas of different types of pyramids. The total surface area of pyramid (TSA) = LSA + base area = (1/2) Pl + B We know that the Total Surface Area of a pyramid (TSA) is obtained by adding the base and lateral surface areas. Hence, the Lateral Surface Area of the pyramid (LSA) = (1/2) Pl (Here, we replaced 4a with P which represents its perimeter.) Therefore, the sum of all side faces (sum of all 4 triangular faces) = 4 = (1/2) × (4a) × l = (1/2) Pl.
