The formula for cubes having two sides painted is
(L-2)x4 + (B-2)x4 + (H-2)x4 Where L = Length, B= Breadth, H=Height
In the above problem it is (4-2)x4 + (3-2)x4 + (3-2)x4
i.e 8 + 4 + 4 = 16
(L-2)x4 + (B-2)x4 + (H-2)x4 Where L = Length, B= Breadth, H=Height
In the above problem it is (4-2)x4 + (3-2)x4 + (3-2)x4
i.e 8 + 4 + 4 = 16
