Explanation:

In the 2nd figure, when the sides of square 5 cm is cut from all corners, length reduces from 45 cm to 35 cm as 5 cm each is cut from 2 extreme ends of the length.
The breadth reduces from 35 cm to 25 cm as 2 squares of side 5 cm each is cut from the extreme ends of breadth.
The Volume of box = length ? breadth ? height. = 35 ? 25 ? 5
= 4375 cm3
