Answer:

V = (x)(10-2x)² . . . . factored form

V = 4x³ -40x² +100x . . . . standard form

Explanation:

A square with corners cut out has no volume. It is a plane figure.

__

We presume you are interested in the volume of the open-top box obtained by folding up each "ear" of the cut figure. The length of each side of its square bottom is 10-2x. The depth of the box is x. So, the volume is ...

V = LWH = (10-2x)(10-2x)(x)

V = x(10 -2x)²

_____

The graph shows the volume is a maximum when x = 1 2/3 cm.
