Two cubes have their faces painted either red or blue.The first cube has five red faces and one blue face.When the two cubes are rolled simultaneously,the probability that the two top faces show the same colour is 1/2. Number of red faces on the second cube,is

In a unit cube. Find The angle between a diagonal of a cube and the diagonal of a face of the cube

Three solid cubes have a face diagonal of 4sqrt(2) cm each. Three other solid cubes have a face diagonal of 8sqrt(2) cm each. All the cubes are melted together to form a cube. Find the side of the cube formed in cm).
