Final answer:
Yes, a one-meter rod can fit inside the box because its length is greater than the smallest dimension of the box.
Step-by-step explanation:
1 meter is equal to 100 cm. The measurements of the box are 40 cm, 40 cm, and 85 cm. To determine if a one-meter rod can fit inside the box, we compare the length of the rod to the smallest dimension of the box. In this case, the smallest dimension is 40 cm. Since the length of the rod (100 cm) is greater than the smallest dimension of the box (40 cm), the one-meter rod can fit inside the box.
