Abox with an open top is to be constructed from a square cardboard, 6 m wide, by cutting out the same small squares from each of the four corners and bending up the sides. find the largest volume that such a box can have. what is the dimension x (in meters) of the small squares that need to be cut out? explain, and show all relevant calculations.

V = (y)^2 * (x)

Step-by-step explanation:

3-2x = y or 3-y = 2x

V = (3-2x)^2 * (x)

V = (4x^2 -12x +9) * (x)

V = 4x^3 - 12x^2 + 9x

dV/dx = 12x^2 - 24x + 9

dV/dx = 0 for maximum: 12x^2 - 24x + 9 = 0

Solve for x using the quadratic formula

x = [-b +-sqrt(b^2-4ac)]/2a

where a = 12, b = -24, c = 9

the answer is b.)

< 1=< 2

i believe the answer is letter c) 8
