Answer: We know that the volume of a cuboid is given by the product of its length, width and height, or V = l * w * h. In this case, the length is 250 cm and the height and width are both x cm. So, the volume can be written as:
V = 250 * x * x
Substituting the given value of V = 4840 cm³, we get:
4840 = 250 * x * x
Dividing both sides by 250, we get:
19.36 = x * x
Taking the square root of both sides, we get:
x = ±√19.36
Since the side length of a square must be positive, we use the positive square root:
x = ±4.4 cm
Therefore, the side length of the square cross-section is 4.4 cm.
