<PRE><B>Question 934746</B>
a. Write an expression to represent the total volume of two different sized boxes as a sum of cubes if one of the boxes has sides with a length of 1 foot and the other has sides with a length of x feet.
V = x^3+1
-------------------
 b. Factor the sum of cubes.
(x+1)(x^2-x+1)
----------------------------------- 
c. Calculate the total volume of the two boxes if x = 3 feet.
V = 3^3+1 = 27+1 = 28 cu ft
