levacccp [35]

Answer:

Max vol = 2 cubic metres

Step-by-step explanation:

Given that from a square piece of cardboard paper of area size 9 m2 , squares of the same size are cut off from each corner of the paper.

Side of the square = 3m

If squares are to be cut from the corners of the cardboard we have the dimensions of the box as

3-2x, 3-2x and x.

Hence x can never be greater than or equal to 1.5

V(x) = Volume = V(x) = x(3-2x)^2\\= 9x+4x^3-12x^2

We use derivative test to find the maxima

V'(x) = 9+12x^2-24x\\V"(x) = 24x-24\\

Equate I derivative to 0

9+12x^2-24x=0\\x=1/2,3/2

If x= 3/2 box will have 0 volume

So this is ignored

V"(1/2) <0

So maximum when x =1/2

Maximum volume

=9(1/2)+4(1/2)^3-12(1/2)^2\\=2 cubic metres
