Consider the same rectangle of the preceding 8 units. Squares of x by x units are cut out of each corner, and then the sides are folded up to create an open box. Express the volume of the box as a polynomial function in terms of x problem. Squares of 2x by 2x units are cut out of each corner. Express the volume of the box as a polynomial in terms of x.

V(x) = l*w*x  - 2*l*x² - 2*w*x² + 4*x³

Step-by-step explanation:

The volume of any box is:

a * b * h       where a is the length, b is the wide and h is the height

Assuming we have cardboard of dimensions: l * w

l - 2*x  will be length  of the box and  

w - 2*x will be wide of the box

h  =  x the height, then:

V(x) = ( l  -  2*x  ) *  (  w  -  2*x ) * x

V(x) = [ ( l*w - 2*l*x - 2*w*x + 4*x² ] * x

V(x) = l*w*x  - 2*l*x² - 2*w*x² + 4*x³

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
