The shape of the core in the square section is square and side value is b/3 & d/3 so the answer is 20 cm.

Here, we can use ((B^2 +D^2)^.5)/6 for calculation.

Its a sq.colum as its dimensions are equal,
For square column,the shape of kern is also square with diagonal = d/3 = 60/3 = 20cm.
Now the Q asks about the side of the core not the diagonal of the core.
But we know that Area of square=1/2(diagonal)^2.
Also area of sq.=a^2,
Solving these two we get a=diagonal/(underroot of 2).
So a=20/(under root 2)= 14.14cm.
