A square piece of cardboard is to be used to form a box without a top by cutting off squares, 3𝑑𝑛 on a side from each corner and then folding up the sides. The volume of the box must be 3000𝑑𝑛3.
1. Draw a diagram to illustrate the given situation.
2. How are you going to represent the length of the side of a square piece cardboard? How about its volume 3. What will be the dimension of the box with a square base?
4. How will you find the length of each side of the box?
If the side of the cardboard is x, then
(x-6)^2 * 3 = 3000
now just solve for x
