### Difficulty Level

Easy### Solution

Option B is the correct answer.

### Option Analysis

Total area of cuboid – area of bottom of cuboid = paper required to wrap all sides except bottom of the cuboid

Total area of cuboid = area of top and bottom side faces (l*b)+area of two side faces(h*b) + area of two side faces (l*h) = 2*25*10 + 2*5*10 + 2*25*5 = 500+100+250=850

Area of bottom face = 250

So paper needed = 850 – 250 = 600 square inches.
