Answer:
V≈3.82×10-7m³
Step-by-step explanation:
If you start with a 12x16 rectangle and cut square with side length x, when you bend the sides you'll have an inner rectangle with sides
and
, and a height of x.
So, the volume will be given by the product of the dimensions, i.e.

The derivative of this function is

and it equals zero if and only if

If we evaluate the volume function at these points, we have

So, the maximum volume is given if you cut a square with side length

7 is a solution
4 is extraneous

If you follow PEMDAS, multiplication would be first, so 3*2 is 6, then it's addition.
So 3*2=6 and 8*-16 is -128, then you add them both.
So 6+(-128) is equals to -122. YOU'RE WELCOME :D
You would multiply 1600 by 5 or divide 1600 by 2 and multiply by 10 to get an answer of 800 milligrams. Then you convert into grams.
