did some body solved that question in today's ph test in which there was a square piece of 30cm and was cut from 4 corners equaly to form a box. find the volume of the box?? what is the answer?

• yup I solved it. Below is the solution
  Let the length of cut be x so it is equal for all four corners. Now the area of base of the box will be (30-2x)*(30-2x). Height of the box is x.
  Volume of the box is (30-2x)(30-2x)*x
  We have to have volume maximum solving above equation we get x=5. putting it in above equation we get volume is 2000.
