Answer:
- 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
