Q. A 24" x 24" square metal plate needs to be fixed by a carpenter on to a wooden board. The carpenter uses nails all along the edges of the square such that there are 25 nails on each side of the square. Each nail is at the same distance from the neighboring nails. How many nails does the carpenter use?

• every corner will have one,4 corners will have 4+ and for 4 sides 23
  no of nails=4+(4*23)= 96

• The four corners of the square have one nail each.
  
  Each side of the square now requires 23 nails (excluding the four corners).
  
  Thus, total number of nails used = 4 + (4 × 23) = 106
