A box with an open top is made from a rectangular piece of cardboard by cutting a square out of each corner and folding up the flaps to form the sides of the box.
----------------------
If the original piece of cardboard is 20 cm by 30 cm, and the squares that are removed each have an edge length of x cm, find a formula for the volume of the box.
----------
base is (20-2x)(30-2x)
---
height is x
------------------
Volume = x(600 - 100x + 4x^2)
---
Volume = 4x^3 - 100x + 600x
==============================
Cheers,
