Hey Balu,
Sorry for the inconvenience but as of now we can't post images here. But I will try to give a detailed explanation so that you understand the question
Let ABCD be a square of side 10. Mark a point L which is at 2cm from A on the line AB. Similarly, mark a point m which is 2 cm from B on line AB proceeding in a similar manner, mark n and o on BC, p and q on CD, and r and s on AD such that s is 2 cm away from A on AD.
So we are removing the squares of side 2 from each of the corners. Let the 4 corners of each of these squares be u, v w and x respectively.
So after removing the squares, the figure which will remain is 'sulmnowpqxr'
Now when we make a cuboid out of it, the length of the cuboid will be lm, breadth will be SR and height will be ul
So the required dimensions are 6*6*2 = 72.
