The length, width, and height of a rectangular box are represented by 4x, x+4, and 3x-2, respectively. When the volume is expressed as a polynomial in standard form, what is the coefficient of the 2nd term?

In the volume expression, coefficient of second term is 40

Step-by-step explanation:

Given,

Length = 4x

Width = x+4

Height = 3x-2

Volume of rectangular box = Length * Width * Height

i. e V = 4x * (x+4) * (3x-2)

V = 12x^3 + 40x^2 - 32x

Here second term is 40x^2 and its coefficient is 40.
