Answer: The new boxes are 14 ft3 larger.
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of each box and compare them.
Volume of a rectangular prism = base x height x length
Replacing with the values given:
Old boxes volume: 4 x 2 x 2 =16 cubic feet
New boxes' volume: 3 x 5 x 2 = 30 cubic feet
Subtraction the old boxes volume to the new boxes volume:
30 ft3- 16 ft3 = 14 ft3
The new boxes are 14 ft3 larger.
