Degree of height:

Degree of volume:

Step-by-step explanation:

A box without a top is to be made from a rectangular piece of cardboard, with dimensions 8 in. by 10 in., by cutting out square corners with side length x and folding up the sides.

(a) Write an equation for the volume V of the box in terms of x.

(b) Use technology to estimate the value of x, to the nearest tenth, that gives the greatest volume. Explain your process

(a) Equation for volume (v):

(8-2x) (10-2x) x=

(80-36x+4x^2) x=

4x^3-36x^2+80x
