Answer: 6</h3>
Work Shown:
E = exterior angle = 60 degrees
n = number of sides of the regular polygon
n = 360/E
n = 360/60
n = 6
The regular polygon has 6 sides.
The volume of a cube = e^3
e = a single edge of the cube.
Area of a square = a^2
a = a single side of the square.
The volume of our cube = 13 ft^3
e =
= 2.35 ft
The area of our square = 4 ft^2
a =
= 2 ft
The edge of our cube is greater than the length of our square's side.
