( This is true for any prism). Let V = Volume, r = radius, h= height. Area of circular base is: Pi x r^2. Taking approximate value of irrational Pi to be 3.14, the area of the base is 3.14 x 7.5^2 = 176.625 sq cm The author has derived the formula to analytically compute all the important parameters of a disphenoid (isosceles tetrahedron with four congruent acute-triangular faces) such as volume, surface area, vertical height, radii of inscribed & circumscribed spheres, solid angle subtended at each vertex, coordinates of vertices, in-centre, circum-centre & centroid of a disphenoid for the optimal. A tetrahedron (triangular pyramid) has vertices and The volume of the tetrahedron is given by the absolute value of D, where Use this formula to find the volume of thetetrahedron with vertices (0, 0, 8), (2, 8, 0), (10, 4, 4), and (4, 10, 6)

A Pyramid is a three-dimensional polyhedron of which one
