The total volume of the purchased boxes is 14x^2+4x+1
Given the following parameters
Volume of a large box = 6x^2+2x+3 cubic units
Volume of medium = 2x^2-5 cubic units.
If a customer purchases two large boxes and one medium box, the total volume is expressed as:
Total volume = 2(6x^2+2x+3) + 2x^2-5
Expand
Total volume = 12x^2+4x+6+2x^2-5
Total volume = 14x^2+4x+1
Hence the total volume of the purchased boxes is 14x^2+4x+1
