Answer:
540°
Step-by-step explanation:
The sum of interior angles in a polygon is equal to 180(x-2) where x is the number of sides. Since there are 5 sides, 180(5-2)=540°.
Volume=legnth times width times height
since it is a cube, legnt=width=height so
volume=height^3 or width^3 or legnth ^3 so
height =5 so
5^3=5 times 5 times 5=125 cubic inches
the answer is C
