Didn't understand the lab explanation of resultant matrix W

In C2_W1_Assignment, section 2.3 Model representation, I don’t understand how the sizes of W1, W2, W3, b1, b2 & b3 calculated?

The sizes are based on the number of features in the dataset and the number of units in each layer.

The rules are given to you

For the first layer, s_{in} is the number of features of your samples.
