It is the sum of the areas of its four 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.
the answer is 120
In the formula for the surface area of a pyramid, "L" typically stands for the slant height of the pyramid. The slant height is the distance from the apex of the pyramid to the midpoint of a side of the base, measured along a triangular face. It is crucial for calculating the area of the triangular faces that make up the sides of the pyramid.
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.
It will be: 4*30mm2 = 120mm2

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.

False, the prism can be of any length.
Surface area of any pyramid is 1/2Pl + B; where P=perimeter of the base, l=slant height and B= Area of the base.
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
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.
