The answer will depend on what aspect the formula is for: the surface area or the volume being the most obvious options.

## Related Questions The formula for finding the volume for a triangular pyramid is half base x height x length. A triangular pyramid has four faces. "triangular" is an adjective - it is not enough to define a shape. You can have a triangular pyramid or a triangular prism and there will be different methods to calculate their volumes. The formula to find the volume of a triangular pyramid is: 1/3 (1/2 B H ) H It depends on triangular what: pyramid, dipyramid, prism, ... The volume for any pyramid = 1/3*base area*perpendicular height  The height of a triangular based pyramid is given by h=2V/(bxl). V is its volume, b its base and l its length.  A pyramid has a base and triangular sides which rise to meet at the same point. The base may be any polygon such as a square, rectangle, triangle, etc. The general formula for the volume of a pyramid is:Area of the base * Height * 1/3 The volume of a pyramid with a rectangular base is equal to: Length_of_base * Width_of_base * Height * 1/3  Volume = 1/3 height of pyramid multiplied by the area of the triangular base. V = 1/3 h * area of base.   You have to find out the area of the base which you find out with perpendicular height times base then time that by the perpendicular height of the pyramid and divide it by 3 The answer is "No"; a right circular cone has a circle as its base while a right triangular cone has a triangular base (which we usually call a "pyramid". The Egyptian Pyramids have square bases. And the volume of any "right" pyramid is found by multiplying the area of its base by its VERTICAL height. A squared + b squared = c saqared (a is a leg), (b is a a leg), (c is a leg) A pyramid has a base and triangular sides which rise to meet at the same point. The base may be any polygon such as a square, rectangle, triangle, etc. The general formula for the volume of a pyramid is: Area of the base * Height * 1/3 The volume of a pyramid with a rectangular base is equal to: Length of base * Width of base * Height * 1/3 the number edges of the base of a pyramid is onr more than the number of faces * * * * * The question had nothing to do with pyramids and, in any case, the answer is wrong! There are different formulae for different aspect of a triangular prism: its volume, surface area, numbers of edges, faces, or vertices. there is no single formula. A pyramid is any three-dimensional polyhedron where the faces other than the base are triangular and converge at one point, called the apex. The formula for finding the volume of a pyramid is . There are some tutorials at the related link below that can help you figure out how to use this formula.  It is not possible to answer this question. The shape could be a triangular prism or pyramid and they will have different volumes. Volume_any_pyramid = 1/3 &times; area_base &times; perpendicular_height For a triangular pyramid (tetrahedron) this becomes: volume = 1/6 &times; base_width &times; base_height &times; pyramid_height For the surface area there is no (easy) general formula: the area of the base triangle and the area of the three side triangles need to be worked out and added together. Volume of a prism = cross-section area*length Volume of a pyramid = 1/3*base area*height The volume of a triangular pyramid can be found using the formula Volume=Base Area x height /3. Surface Area can be expressed as Surface Area =Base Area+0.5 x perimeter x side length. go to this website... it has a diagram and equation http://www.mathsteacher.com.au/year10/ch14_measurement/25_pyramid/21pyramid.htm
