Asolid has faces that consist of 8 equilateral triangles. what type of solid is it? how many edges does it have? a. dodecahedron; 10 edges b. octahedron; 12 edges c. octahedron; 14 edges d. dodecahedron; 16 edges

Option 'B' is correct.

As it is octahedron and it has 12 edges.

Step-by-step explanation:

Since we have given that

A solid has faces that consist of 8 equilateral triangles.

So, it will be "Octahedron" which is a special type of polyhedron with eight faces twelve edge and six vertices.

It is composed of eight equilateral triangle.

Hence, Option 'B' is correct.

As it is octahedron and it has 12 edges.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
