Problem 55295. Chain multiplication - 01

Say, you are given two matrices - A (shape= 3*4) and B(shape = 4*5).
If you multiply these two matrices, the resultant matrix will be of shape - 3*5.
To obtain the resultant matrix, you will need to perform in total 60 multiplications internally between the elements of the matrices (can easily be checked from matrix multiplication rule).
The first question is - if you are given just two matrices, what will be the total number of multiplications needed to obtain the resultant matrix.
