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. The volume formula for a triangular prism is (height x base x length) / 2, as seen in the figure below: So, you need to know just three measures: height, base, and length, in order to calculate the volume. Units: Units are shown for convenience but do not affect calculations. Height is calculated from known volume or lateral surface area. Use this triangular prism calculator to easily calculate the volume of a triangular prism or tank from its length, base, and height in any metric: mm, cm. shows a right rectangular prism, and Figure 8.23 shows a right triangular prism. First, plug in the values for the area formula of a triangle to find the base area, B. Surface area calculations include top, bottom, lateral sides and total surface area. Example 2 Find the volume of a prism Find the volume of the Toblerone. (some times we need too divide it by 2 or 3 and in case of a triangular prism we need to divide the product of base area and height by 2). ![]() This calculator finds the volume, surface area and height of a triangular prism. The volume of a prism is VBh B is the area of the base of the prism h is the height of the prism The base of our prism is a triangle, so we can use (1/2)bh. The resulting output from our triangular prism calculator is always in cubic units: in3, ft3, yd3, mm3, cm3, meters3, etc. A triangular prism is a 3D solid formed by putting rectangles and triangles together. Make sure they are all in the same length unit, or convert accordingly until they are. It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles. You need to take or know (from a plan/schematic) three length measurements. ![]() 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.
