- 26

Step-by-step explanation:

The volume (V) is calculated as

V = lwh ( l is length, w is width, h is height ), then

V = 2x(3x + 1)(5x - 6) ← expand the factors using FOIL

   = 2x(15x² - 13x - 6) ← distribute parenthesis by 2x

   = 30x³ - 26x² - 12x

The second term is - 26x² with coefficient - 26
