4*50 = 200 cm2.
the answer is 120
It will be: 4*30mm2 = 120mm2
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
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
It will be: 4*30mm2 = 120mm2
If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres

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.
In geometry, pyramid has many forms such as rectangular pyramid, trapezoidal pyramid, quadrilateral pyramid and even triangular pyramid. Triangular pyramid is a pyramid with triangular base and can be called as a tetrahedron if each of its faces has congruent equilateral triangles.
A triangular pyramid is a pyramid having a triangular base. The tetrahedron is a triangular pyramid having congruent equilateral triangles for each of its faces.
to find the surface area you have to first find the area of each part then add the areas together.
