Answer: V = (d+1)^3

That expands out to
V = d^3 + 3d^2 + 3d + 1

============================================================

Work Shown:

d = diameter of the ball
d+1 = one inch larger than that diameter = side length of the cube

V = volume of the cube
V = (side)*(side)*(side)
V = (side)^3
V = (d+1)^3

Optionally we can expand that out
V = (d+1)^3
V = (d+1)(d+1)^2
V = (d+1)(d^2+2d+1)
V = d(d^2+2d+1)+1(d^2+2d+1)
V = d^3+2d^2+d+d^2+2d+1
V = d^3+(2d^2+d^2)+(d+2d)+1
V = d^3+3d^2+3d+1

The Binomial Theorem is another approach you could take to go from (d+1)^3 to d^3+3d^2+3d+1
