A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.

A pentagonal prism has 5 faces, with each face having 5 vertices. Each vertex connects two adjacent faces, forming a total of 10 right angles around each vertex. Therefore, a pentagonal prism has a total of 50 right angles.
The shape you are describing is a triangular pyramid. A triangular pyramid has a base that is a triangle and three triangular faces that meet at a single point called the apex. The base of the pyramid is a rectangle, which is a quadrilateral with four right angles. The triangular faces of the pyramid connect the vertices of the base to the apex.
the defnition of find the surface area of triangular prism and cylinder
The volume of a three-dimensional figure is the amount of space it encloses. The volume V of a triangular prism is the product of the area B of a base and the height h of the prism. (The bases are triangles. In a special case of a right triangular prism the bases are right triangles)
There are at least 30 angles between edges in a right pentagonal prism. If the entlgon is regular there are two different vlues for these angles; 90 and 108 degrees.
