Answer 1

Answer:

Carpenter uses 116 Nails

Step-by-step explanation:

30 nails on each side of the square

if we ignore Nails at extreme corner then

Nails on each edge = 30 - 2 = 28 Nails

Nails on all the four edges = 4 * 28 = 112  Nails

& 4 Nails on the four corner of Square

Then total number of Nails = 112 + 4 = 116 Nails

Carpenter uses 116 Nails
