Is the formula given by @Shekhar applicable for any cuboid to find cubes with two side painted?

Its the right explanation. If you go through it practically you would surely get it right.

I think so 4 from left and 4 from right. 4 cubes have two face colored.

Since there are 12 edged in the cube front face have 2 faces such as 2 sides painted so total 2*4 (edges of 2 sides painted), similarly when you go by height 1*4, and same breadth 1*4.
So, total (2*4 + 1*4 + 1*4) = 16.
So, total (2*4 + 1*4 + 1*4) = 16.
