Here, Length of box = l = 20 cm Breadth of box = b = 10 cm Height of box = h = 3 cm Now,  Volume of box = l × b × h = 20 × 10 × 3 =600 .....

Remember : Volume = Cross section Area × height = 20 m2  × 5 m = 100 .....

Given by the question. Length(L) = 25 m  By using formula, Perimeter of the square is P = 4L or, P = 4 ⨉ 25  ∴ P = 100 m  The perimeter of a square is 100 .....
