A rectangular box is built by cutting out square corners from a

9" by 11" piece of cardboard, then folding the resulting flaps up to form the height. Let x represent the sides of the square corners being cut out. Express the volume of the box as a function of x.
V(x)=_____________________.
What will the volume be if 1" squares are cut out?
With 1 squares cut out, the volume will be __________ cubic inches.

1 answer

V(x) = x (9 - 2x) (11 - 2x)

plug in 1 for x and solve for V
