Help with finding the max volume of a box?
You are planning to make an open rectangular box from a 10 by 18 cm piece of cardboard by cutting congruent squares from the corners and folding up the sides.
(a) what are the dimensions of the box of largest volume you can make this way?
(b) what is its volume?
click on the link;
V = ∫ (10 - 2x)(y)(x)
but;
18 = y + 2x
y = 18 - 2x
V = ∫ (10 - 2x)(18 - 2x)(x)
V = ∫ (10x - 2x^2)(18 - 2x)
∂V/∂x = (10x - 2x^2)(-2) + (18 - 2x)(10 - 4x)
equate ∂V/∂x to zero;
0 = (-20x +4x^2) + (180 - 72x - 20x + 8x^2)
combine like terms;
0 = 12x^2 -112x + 180
divide both side by 12, we get;
x^2 - (28/3)x + 15 = 0
I HAVE DONE MY PART, It's your turn to simplify the equations,
Hint:
If you get the value of x, subtitute to y = 18 - 2x
and you're done!
GOODLUCK!!!
