To calculate the size of the convoluted matrix, we use the generalized equation, given by:

**C = ((n-f+2p)/s)+1**

**where,**

**C** is the size of the convoluted matrix.

**n** is the size of the input matrix.

**f** is the size of the filter matrix.

**p** is the Padding amount.

s is the Stride applied.

Here n = 12, f = 3, p = 0, s = 1

Therefore the size of the convoluted matrix is 10 X 10.
