Volume of a rectangular prism is ~

$\sf{Volume_{cuboid}= Length × Width × Height}$

$\qquad \sf \dashrightarrow \: v = (4x + 2) \times (3x - 5) \times (7x + 4)$

$\qquad \sf \dashrightarrow \: v = (12 {x}^{2} - 20x + 6x - 10) \times (7x + 4)$

$\qquad \sf \dashrightarrow \: v = (12 {x}^{2} - 14x- 10) \times (7x + 4)$

$\qquad \sf \dashrightarrow \: v = 84 {x}^{3} + 48 {x}^{2} - 98x {}^{2} - 56x - 70x - 40$

$\qquad \sf \dashrightarrow \: v = 84 {x}^{3} - 50 {x}^{2} - 126x - 40$

So, the correct choice is B
