# How do you 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 others has sides with a length of x feet?

Volume of 1 ft cube box: ${V}_{1} = {1}^{3}$
Volume of $x$ ft. cube box: ${V}_{x} = {x}^{3}$
Total Volume: ${V}_{T} = 1 + {x}^{3}$
