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)
A regular tetrahedron, with edges of length 1 units, has a total surface area of sqrt(3) square units.

The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . . If it is known is N-face surface area of ​​the body, there are N +1 is smaller the surface area of ​​the surface When N tends to infinity for a long time, Serve the sphere surface. ------mecose
To find the total surface area of a tetrahedron, you need to calculate the area of each of its four triangular faces and then sum these areas. The area of a triangle can be found using the formula ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ) or using Heron's formula if the side lengths are known. Once you have the areas of all four faces, add them together to obtain the total surface area of the tetrahedron.
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.
