Final answer:
After Fin adds one more box to the original 112 cm tall tower, the tower becomes 128 cm tall, as each box is 16 cm in height.
Step-by-step explanation:
The question involves calculating the new height of a tower made by stacking identical cube-shaped boxes. Originally, there are 7 boxes making the tower 112 cm tall. To find the height of each individual box, we divide the total height of the tower by the number of boxes:
Height of each box = Total height of tower / Number of boxes
Height of each box = 112 cm / 7
Height of each box = 16 cm
When Fin adds 1 more box, we will add that box's height to the original tower's height:
New height of tower = Original height + Height of one box
New height of tower = 112 cm + 16 cm
New height of tower = 128 cm
Therefore, after Fin adds one more box to the tower, it is now 128 cm tall.
