Answer:
the second box
Explanation:
To determine which box would use more material to make, the volume of the boxes have to be determined. the box with the larger volume would require more material to make
Volume of a box = length x breadth x height
Volume of box 1 = 8in x 6.25in x 10.5in = 525 in³
Volume of box 2 = 9in x 5.5in x 11.75in = 581.6 in³
the second box has a larger volume and thus would need more material to make
