Question

Geometry B Unit 6: Surface Area and Volume, Lesson 10: Surface Area and Volume Unit Test?

Answer 1

Answer:

B

Step-by-step explanation:

Euler's formula for polyhedra states that

F + V - E = 2

where F is faces, V is vertices and E is edges

Substitute the values given and solve for F, that is

F + 13 - 26 = 2

F - 13 = 2 ( add 13 to both sides )

F = 15 → B
