First, Corey should calculate the area of one of the equilateral triangles using the formula A = 1/2 x base x height.
A = 1/2 x 5 inches x 4.33 inches = 10.825 square inches.
Since there are four congruent triangles making up the tetrahedron, Corey should multiply the area of one triangle by 4 to find the total surface area of the tetrahedron.
Total surface area = 10.825 square inches x 4 = 43.3 square inches.
Therefore, the surface area of the tetrahedron is 43.3 square inches.
Corey is 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 Corey do next? Help Corey to find the surface area of the tetrahedron

but it together
I apologize for providing the surface area in square units instead of inches squared. To find the surface area of the tetrahedron, Corey should calculate the total area of the four equilateral triangles in inches squared:
Total surface area = 10.825 square inches x 4 = 43.3 square inches.
Therefore, the surface area of the tetrahedron is 43.3 square inches.
Total surface area = 10.825 square inches x 4 = 43.3 square inches.
Therefore, the surface area of the tetrahedron is 43.3 square inches.
no I mean put it in a sentence
Corey should put it in a sentence in the following way:
"The surface area of the tetrahedron, made up of four congruent equilateral triangles with a base of 5 inches and a height of approximately 4.33 inches each, is 43.3 square inches."
"The surface area of the tetrahedron, made up of four congruent equilateral triangles with a base of 5 inches and a height of approximately 4.33 inches each, is 43.3 square inches."
