It is a rectangular based pyramid
A rectangular pyramid has 5 faces: a rectangular base, and 4 triangular faces.
You find the area of the base and then find the area of one triangle. Multiply that one triangle by 4 and then add the base. The above is correct for a triangular pyramid NOT a triangilar prism. A triangular prism has two triangular ends and three rectangular faces. The rectangular faces need no be the same shape, but if they are, So Area = 2*area of triangular ends + 3*area of rectangular faces If not, you'll just have to calculate each area separately and add them.
There are an infinite no of shapes that have exactly 4 triangular faces. The two commonest are a tetrahedron and an Egyptian pyramid. If the question is re-phrased to "What shape has exactly four faces, (all of which are triangular), then the only answer is a tetrahedron. An Egyptian pyramid has five faces - a square base and four triangular sides. It is regular (the apex is vertically above the center of the base) and the sides are isosceles.
A shape with 5 sides is a pentagon.However, the term face is only applied to three-dimensional forms,and a shape (solid) with 5 faces is a pentahedron.There are no regular pentahedrons. The two forms are the square pyramid and the triangular prism. The former has 4 triangular sides and a square or rectangular base; the latter has 3 rectangular (or square) faces and two triangular ends.
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.
