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.

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.

It is 288 cm^2.

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.

False, the prism can be of any length.

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
