Coreys trying to find the surface area of a tetrahedron They sketch a net of the tetrahedron on their paper. The net shows four congruent equilateral triangles each with a base of 5 inches and a height of approximately 4.33 inches. What should Cory do next help Cory to find the surface area of the tetrahedron .

Answer 1

To find the surface area of a tetrahedron, Cory can use the formula:

Surface Area = √3 * s^2

where s is the side length of the equilateral triangle.

Since each equilateral triangle in the net has a base of 5 inches, the side length is also 5 inches. Therefore, Cory should plug in 5 for s in the formula:

Surface Area = √3 * 5^2
Surface Area = √3 * 25
Surface Area = 25√3

Cory should multiply 25 by the square root of 3 to find the surface area of the tetrahedron. This will give him the final answer in square inches.
