1. triangular prism it has 2 triangular faces. 2.triangular base pyramid, it has 5 triangular faces. 3. square base pyramid, it has 4 triangular faces.
A triangular prism has three rectangular faces and two triangular faces.
If you mean a triangular pyramid then it has four faces, one base and three sides.
A Hexahedron has no triangular faces. A Tetrahedron has 4 triangular faces. A octahedron has 8 triangular faces. A Icosahedron has 20 triangular faces. By:-Cherrylvr- :)
It is the sum of the areas of its four 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.
The first comprises one rectangular face and four triangular faces whereas the second has two triangular and three rectangular faces.
Like all prisms you find the area of one of the triangular faces and then multiply by the height.

There are infinitely many polyhedra with one or more triangular faces.
By doing the area for a triangle :)
A triangular prism has three rectangular faces and two triangular faces.
To work out the area of the rectangular faces, you need to multiply the length by the width. You then need to multiply that answer by 3 (because there are 3 rectangular faces).To work out the area of the triangular faces, multiply the base of the triangle by the height and divide the answer by 2 (to find the area of one triangle). You then need to multiply it by 2 again because there are 2 triangular faces.Important: The height of a triangle is the distance from the top corner of the triangle down to the base (so that it meets the base at 90 degrees)You then need to add the total surface area of the rectangular faces to the surface area of the triangular faces to get the total surface area of the entire prism.(sorry for the essay :])
Any one of the four triangular faces.

It is a hexahedron. There are several types of hexahedron, one of which is the cube. One having 6 triangular faces is a triangular dipyramid.
