![]() Triangular Prism Formulas in terms of height and triangle side lengths a, b and c: Volume of a Triangular Prism Formulaįinds the 3-dimensional space occupied by a triangular prism. Significant Figures: Choose the number of significant figures or leave on auto to let the calculator determine number precision. Answers will be the same whether in feet, ft 2, ft 3, or meters, m 2, m 3, or any other unit measure. It is found by multiplying the length (l) and width (w) of the base, and then multiplying that. ![]() This term represents the area of the two bases (top and bottom) of the prism. You need to pick the right triangle option (this option serves as the surface area of a right triangular prism calculator ). In the given formula for the surface area of a right rectangular prism, which is A 2lw + 2hw + 2lh, the term that does not depend on the height (h) is the first one, 2lw. Units: Units are shown for convenience but do not affect calculations. If only two sides of a triangle are given, it usually means that your triangular face is a right triangle (a triangle that has a right angle 90 between two of its sides). The back face is the same as the front face so the area of the back is also 30cm2 30cm2. To calculate the surface area of triangular prisms, you need to calculate the area of each face and add them all together. The area of the triangle at the front is 1 2 ×12×530cm2 21 × 12 × 5 30cm2. The formulas for LSA and TSA are given as: Total Surface Area of an Equilateral Triangular Prism. The surface area formula for a triangular prism is 2 (height x base / 2) + length x width 1 + length x width 2 + length x base, as seen in the figure below: A triangular prism is a stack of triangles, so the usually triangle solving rules apply when calculating the area of the bases. Formulas for Surface Area of a Right Triangular Prism. Height is calculated from known volume or lateral surface area. Example 1: finding the surface area of a triangular prism with a right triangle. 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. 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. 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. Here are the steps to compute the surface area of a triangular prism: 1.
