I hope that answer was helpful to you! Let me know if you have any other questions.

How do you know

To find the volume of each sandbox, you multiply the width, length, and height of each box.

For Box A: 9 inches x 13 inches x 15 inches = 1755 cubic inches
For Box B: 6 inches x 12 inches x 20 inches = 1440 cubic inches

Then, you calculate the difference in volume:
1755 cubic inches - 1440 cubic inches = 315 cubic inches

Therefore, the difference between the volumes of the two sandboxes is 315 cubic inches.

I hope this explanation helps clarify how the answer was reached. Let me know if you have any other questions!
