The volume of a triangular pyramid can be found using the formula Volume=Base Area x height /3. Surface Area can be expressed as Surface Area =Base Area+0.5 x perimeter x side length.

It is 288 cm^2.

False, the prism can be of any length.

The first comprises one rectangular face and four triangular faces whereas the second has two triangular and three rectangular faces.

If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres

If it is a triangular pyramid it would be (1/2bh)4 A triangular prism is (1/2bh)5, or (base x height divided by 2)times 4

The answer will depend on what aspect the formula is for: the surface area or the volume being the most obvious options.

The volume of a triangular pyramid can be found using the formula Volume=Base Area x height /3. Surface Area can be expressed as Surface Area =Base Area+0.5 x perimeter x side length.

a pyramid with a triangular base has 4 faces. a pyramid with a square base has 5 faces.

It is the sum of the areas of its four faces.

To calculate the surface area of a truncated pyramid, you first take the surface area of each side. That would be the base time the straight height. If it is a 4 side pyramid with equivelant sides, multiply that answer by 4.

Volume_any_pyramid = 1/3 × area_base × perpendicular_height For a triangular pyramid (tetrahedron) this becomes: volume = 1/6 × base_width × base_height × pyramid_height For the surface area there is no (easy) general formula: the area of the base triangle and the area of the three side triangles need to be worked out and added together.

The faces are the flat, triangle-shaped surfaces that make up the surface of the pyramid. A pyramid has four faces.

Surface area of a triangular pyramid: SA = 1/2 as + 3/2 sl a = altitude of the base triangle s = side of the triangle l = slant height of the pyramid.

Calculate the area of the 2 triangles first, which is base multiplied by height, then divided by 2. Then find the area of the 3 rectangles, which is length multiplied by width. Finally, just add all the areas together, and there you go! You get the surface area! :D <3
