If its a triangular based pyramid (tetrahedron) then it will have 4 equilateral triangle faces and so find the area of one face and multiply it by 4 to give the total surface area.
It is the sum of the areas of its four faces.
the answer is 120
It will be: 4*30mm2 = 120mm2
4*50 = 200 cm2.
If its a triangular based pyramid (tetrahedron) then it will have 4 equilateral triangle faces and so find the area of one face and multiply it by 4 to give the total surface area.
It is 288 cm^2.
It is the sum of the areas of its four faces.
the answer is 120
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.
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 will be: 4*30mm2 = 120mm2
False, the prism can be of any length.
If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
4*50 = 200 cm2.
The first comprises one rectangular face and four triangular faces whereas the second has two triangular and three rectangular faces.
