A box is shaped like an octagonal prism. What is the area of the base

Step-by-step explanation:

An octagonal prism is a polyhedron consisting of two equal and parallel faces called base. In an octagonal prism its bases are shaped like an octagon. Therefore, the area of the base of this box is basically the area of an octagon.

An octagon is a flat geometric figure consisting of 8 sides and 8 vertexes. The area of a regular octagon of side length is given by:

what i would say the best answer is a. 40.5

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
