From the four corners of a rectangular sheet of dimensions $$25cm \times 20cm$$, square of side 2 cm is cut off from four corners and a box is made. The volume of the box is
The diagram given below describes the scenario (figure not to scale)
When squares of side 2 cm are cut, the remaining paper can be folded to make a box, with length 25-2-2=21 cm, breadth 20-2-2=16 cm and height 2 cm.
So its volume will be lbh=21x16x2= 672 cm cube. So the correct answer is option B.
