It is 1/2*base*height of the triangle.
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.
To find the total area of the triangular faces of a pyramid, first identify the number of triangular faces and their base and height dimensions. For each triangular face, use the formula for the area of a triangle: ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ). Calculate the area for each triangular face and then sum these areas to get the total area of all triangular faces.
A triangular pyramid, or tetrahedron, has four triangular faces. If each face has an area of 80 m², the total surface area can be calculated by multiplying the area of one face by the number of faces: (4 \times 80 , \text{m}^2 = 320 , \text{m}^2). Therefore, the surface area of the triangular pyramid is 320 m².
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.
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.
Like all prisms you find the area of one of the triangular faces and then multiply by the height.
The first comprises one rectangular face and four triangular faces whereas the second has two triangular and three rectangular faces.

There are infinitely many polyhedra with one or more triangular faces.
By doing the area for a triangle :)
Any one of the four 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.
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 :])
