A tetrahedron is a pyramid with 4 equilateral triangular faces, 6 edges and 4 vertices.
Each edge: 42/6 = 7 cm
Total surface area: 0.5*7*7*sin(60 degrees)*4 = 85 square cm to the nearest integer
A regular tetrahedron, with edges of length 1 units, has a total surface area of sqrt(3) square units.
It depends on whether or not the tetrahedron is regular. There is nothing in the question to indicate that it might be regular. In that case the easiest way to calculate the surface area is to sum the areas of each of its 4 faces.

To arrange four points at equal distances on the surface of a sphere, you can position them at the vertices of a regular tetrahedron. Each vertex of the tetrahedron is equidistant from the others, ensuring that the points are evenly spaced. This arrangement maximizes the distance between each pair of points on the sphere's surface. Since the tetrahedron is symmetrical, it provides a uniform distribution of the points.

Curved surface area = pi*2*15 = 94 square meters (to nearest integer)
If each edge is 5 units long, then the total surface area is 5*sqrt(3) = 8.6603 square units, approx.
A 3D triangle, commonly referred to as a tetrahedron, has four flat surfaces. Each surface is a triangle, and the tetrahedron is the simplest form of a polyhedron. It consists of four vertices and six edges as well.

If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres
A tetrahedron is a solid figure with four triangular faces. As these may or may not be regular (all the same), the formula is to add the area of all four together. The formula for the area of a triangle is 1/2(base x height).
