It is not a standard finished commodity lumber size. Most likely the member you are looking at is a 2x8, which measures 1-1/2" x 7-1/4".
I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
