The area of required paper is 3125 sq.cm.

Step-by-step explanation:

Side of cubical tin = 25 cm

Cubical tin is without lid

So, Surface area of tin = Lateral surface area + 1 base

Surface area of tin =$4a^2+a^2$

                                =$5a^2$

                               =$5(25)^2$

                               =$3125 cm^2$

So,the area of required paper is 3125 sq.cm.
