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.

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

32 divided by 8 is 4 inches

A regular octahedron has 8 faces. If the total surface area is 32 square inches then each face have a surface area equal to one eighth of this. 32/8 = 4 so the surface area of each face is 4 square inches

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).

No. In fact, surface area is never measured in inches.

The total surface area is 606.32 square inches. The lateral surface area is 405.25 square inches.

The total surface area is 400.21 square inches. The lateral surface area is 287.11 square inches.

Total surface area = 314.16 square inches. Lateral surface area = 157.08 square inches.
