See below for graph of the Surface Area, and note its minimum occurs when s = 28.87. The surface area is expressed in square units. Here are the steps to compute the surface area of a triangular prism: 1. The volume of the prism is \(\displaystyle 6013=\frac \ = \ 6012.695 \ - \ good \ enough \ for \ government \ work.\) The surface area of a triangular prism is equal to the sum of the area of tree lateral surfaces and the two bases. A triangular pyramid has four triangular faces. We can express a in terms of s also, because we have the given volume.Īfter substituting h and a into the expressions for the three rectangles' area and two triangles' area, followed by adding the results, I get the function for total surface area A, in terms of s: Explanation: If you think it is too long to remember, just find the area of each of the shapes on it and add them together. The surface area of any three-dimensional geometrical shape is the sum of the areas of all of the faces or surfaces of that enclosed solid. Three congruent rectangles and two congruent triangles comprise the total surface area.įrom the Pythagorean Theorem, we know that h = sqrt(3)/2 * s. I get a different function for the total suface area, in terms of s.īTW, it's helpful if you define your variables and constants, so that other people will know what you're thinking. Implement this fact and find the surface areas of the prisms with bases in the shapes of equilateral, isosceles, scalene, and right triangles in these pdf worksheets, ideal for students of grade 6 through high school. The formula for finding the surface area of a triangular prism is given as: A bh + L (s1 + s2 + s3) Where A is the surface area, b is the bottom edge of the base triangle, h is the height of the base triangle, L is the length of the prism, and s1, s2, and s3 are the three edges of the base triangle. The given dimensions do not produce a volume of exactly 6,013 ml. Simply put, the surface area of a 3d figure is nothing but the area of its net.
