![]() Step 4: Find the lateral area of the pyramid. Find the area, surface area, and volume of a right square (right rectangular) pyramid with the given side length 3, height 4, and slant height 5. Step 2: Find the surface area of the pyramid. Find the area, surface area, and volume of a triangular pyramid with the given apothem length 2, side 3, height 4, and the slant height 5.Īrea of the base (A) = ½ * a * s = 0.5 * 2 * 3 = 3. Wondering how to find the surface area of a pyramid? Let’s find it step by step in this section. Surface area of a triangular pyramid calculator It is a structure where the upper surfaces are triangular and converge on one point. Surface Area of Pyramid : Ī pyramid is a polyhedron with one face as a base, a polygon, and all the other faces of triangles meeting at a common polygon vertex as the apex. The above equation can be used to calculate the square pyramid volume. In case you don’t want to get stuck in equations, a pyramid volume calculator can ease your calculations of a pyramid. It composes the required formula in the run time after gathering the values and that is why it is safe to say that it is also a surface area of a triangular pyramid formula calculator. The pyramid area calculator automatically utilizes the relevant formula and calculates the area, volume, base, and other terms accordingly. A pyramid is a three-dimensional structure and a polyhedron. What is a pyramid?Ī pyramid is a solid object having a polygon base and triangular sides that meet at the top. It offers a one-stop-shop for all calculations of a pyramid. It doesn’t matter if you want to find the surface area, volume, base area, base width, or base length. The surface area of triangular pyramid calculator handles all pyramid related calculations like a pro. ![]() Thus, the point we have found is a local minimum.Triangular Pyramid Surface Area Calculator The second derivative of this guy is strictly positive for positive s, implying the function is concave up for positive s. To do so you must take the second derivative. We'll end up with h = 2 * 5 2/3 *7 1/3 / sqrt(3).ĮDIT: It's a bit pedantic, but technically you have to make sure that it's a local minimum at the value of s that I've found. From there, we can easily find the height by substituting into our previous formula. We want to find the minimum so we set SA' = 0. SA = 2(sqrt(3)/4)s 2 + 3sh (the first term is the 2 triangular parts and the second term is the three lateral, rectangular parts).Īs a function of s alone, we have SA = 2(sqrt(3)/4)s 2 + 4sqrt(3)350/s. This is equivalent to h = 4*350/(sqrt(3)s 2 ). V = (sqrt(3)/4)hs 2 = 350 cm 3 (I converted mL to cm 3 for ease). ![]() Then the area of the base is (sqrt(3)/4)s 2. Let s be the base of the triangle and h be the height. This is an ordinary optimization problem so it requires the use of basic calculus.
