The answer would be 480 because there are four sides and each is 120 so you just multiply 120 by 4!! ;)
the answer is 120
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.
It will be: 4*30mm2 = 120mm2
4*50 = 200 cm2.
To find the surface area of a pyramid using a net, first, draw the net by unfolding the pyramid into its flat shapes, which include the base and the triangular faces. Calculate the area of the base and the area of each triangular face separately. Finally, sum the areas of all the shapes in the net to obtain the total surface area of the pyramid.

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

Find the surface area of each of the four triangular faces (they need not be the same) and sum the individual areas.
As stated, the question cannot be answered. The pyramid could be irregular so that its triangular faces have different areas. If it were a regular pyramid, then with a square base it has four triangular faces whose combined area is 189 - 49 = 140 cm2 So each triangular face has an area of 140/4 = 35 cm2
To calculate the surface area of a regular pyramid, you need to find the area of the base and the area of the triangular faces. The surface area (SA) can be expressed as SA = Base Area + Lateral Area. For a square base, the base area is the side length squared, and the lateral area is found by calculating the area of each triangular face and summing them. If you provide the base side length and the height of the pyramid, I can help calculate the exact surface area.
4*30 = 120 mm2
Each of them has four triangular faces.
YesA triangular pyramid is a pyramid having a triangular base. The tetrahedron is a triangular pyramid having congruent equilateral triangles for each of its faces.
