Squares of the same size cut from the four corners of a rectangular cardboard with dimensions 30 cm by 20 cm. After cutting, the cardboard is folded to make an open box. What is the length of the box? ​

Answer:

30-2x cm

Step-by-step explanation:

It depends in the dimension of the square.

Let's say the side is going to be x.

The length of the box would be 30 - 2x cm.

Example:

If you are going to take out a square of side 3cm, you are going to cut 3cmx3cm from left and from right. So length 30cm now would decrease to 30 - 3*2 cm = 24cm.
