The formula to find the volume of a triangular pyramid is: 1/3 (1/2 B H ) H
It is 1/3*(base area)*(vertical 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.
The formula for a triangle-base pyramid (a form of tetrahedron) isV = 1/3 Bh where B is the area of the triangular baseFind the area of the base by the formula B = 1/2 bh (height of that triangle), then multiply by 1/3 of the pyramid'sheight.
In geometry, pyramid has many forms such as rectangular pyramid, trapezoidal pyramid, quadrilateral pyramid and even triangular pyramid. Triangular pyramid is a pyramid with triangular base and can be called as a tetrahedron if each of its faces has congruent equilateral triangles.
