which expression represents the volume of the box?
use the formula v=lwh
a.6x^3-2
b. 6x^3+x-2
c. 6x^3-13x^2-3x-2
d.6x^3+5x^2-3x-2
and explain how you got your answer i’ve been stuck on it for days and i can’t figure it out.

D. 6x³ + 5x² - 3x - 2

Step-by-step explanation:

First assign each variable with its number.

l = 2x + 1

w = x + 1

h = 3x - 2

Now, plug in.

v = (2x + 1)(x +1)(3x - 2)

Now combine the first two pairs following the FOIL method. (First Outer Inner Last)

(2x² + 3x + 1)(3x - 2)

Now you would multiply the 3x on to each term and the -2 on to each term.

6x³ + 9x² + 3x - 4x² - 6x - 2

Now combine like terms.

6x³ + 5x² - 3x - 2

i just took the test, the correct answer is .. 31.5 in.
