Answer:
the volume of the box increases 48 times compared to the 1st one.
Step-by-step explanation:
Volume of the box (1) = LWH
- length of a box is increased 4 time = 4L
- width is increased 4 times = 4W
- the height is tripled = 3H
=> The new volume of the box = 4L * 4W * 3H = 48LWH
So the volume of the box increases 48 times compared to the 1st one.
