Answer:
V = L^3 where v is volume and L the length of one side
A = 6 * L^2 total area of cube with side L
A = 6 * V^2/3 area of cube expressed in V
A2 / A1 = (V2 / V1)^2/3 6 cancels
A2 / A1 = 8^2/3 = 4 ratio of areas
Divide 6 by 3
3 goes into 6, 2 times so one apple costs $2
That would be 8/7 or 1 1/7. Hope this helps! :)
