Answer:
(x -10) and (x+10)
Step-by-step explanation:
The volume of a box is V = l*w*h. Here the w = 6 and V = 6x² - 600. Divide the volume of the width 6 to find possible values for length and height.
6x² - 600 / 6
x² - 100
The length and width can be anything that multiply to x² - 100.
(x-10)(x+10) are possible amounts.
