Final answer:
To find the corners and folding up the flaps, we need to determine the value of x in the given question. The volume of the box can be calculated by multiplying its length, width, and height. We can solve the equation (30 - 2x)(70 - 2x)(x) = 6272 to find the value of x.
Step-by-step explanation:
To find the corners and folding up the flaps, we need to determine the value of x in the given question. Let's start by drawing a diagram of the open-topped box. Since the box is formed by cutting squares of width x from the corners of a rectangle, the length and width of the resulting box will be reduced by 2x. The height of the box will be equal to x.
The volume of the box can be calculated by multiplying its length, width, and height. So, we have:
(30 - 2x)(70 - 2x)(x) = 6272
Now, we solve this equation to find the value of x.
