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

What the total surface area of the regular tetrahedron?
A regular tetrahedron, with edges of length 1 units, has a total surface area of sqrt(3) square units.
What is the formula to find the surface area of a tetrahedron?
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.
What is the approximate surface area of a regular tetrahedron with edge length 10 cm?
173
Why sphere has minimum surface area for given volume?
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
