an open top box is to be constructed from a rectangular piece of cardboard measuring 52 cm by 36 cm. box is created by cutting congruent corners and then folding up the sides. 

a) express the volume of box as function of x.

b) use the function from part a) to determine value(s) of x, to 2 decimal places, that will result in a volume greater than 3024 cm cubed.

c) determine the dimensions of box for volume given in part b)

myy work so far:

a) let x be the sides being cut off from corners , therefore

p(x) = x(52-2x)(36-2x)

now i dont dont know how to do inequalities part b).. O__0

I get your point now. Let me think about it for a second.

exactly... 😆😆😆 u can't stop..

and how can u expect me to stop??? 😆
