A solid cube is divided into $27$ smaller cubes of equal volume. If two opposite faces of this bigger cube are painted with different colours and remaining faces are left unpainted, then how many smaller cubes are obtained which have no faces painted?

Read the following information carefully and answer the question given below. A solid cube has been painted yellow, blue and black on the pair of opposite surfaces. The cube is then cut into $36$ smaller cubes such that $32$ cubes are of the same size while $4$ others are of a bigger size. Also, no face of any of the bigger cube is painted blue.

How many cubes have only one face painted?

Read the following information carefully and answer the question given below.

Two adjacent faces of a solid cube have been painted red and the faces just opposite to the red painted faces have been painted black while the remaining faces have been painted green. After painting this, cube has been divided into $64$ smaller cubes.

How many cubes have two adjacent faces painted in red or black?

Read the following information carefully and answer the question given below. A cuboid of dimensions $\left(6 \mathrm{cm}\times 4 \mathrm{cm}\times 1 \mathrm{cm}\right)$ is painted black on both the surfaces of dimensions $\left(4 \mathrm{cm}\times 1 \mathrm{cm}\right)$, green on the surfaces of dimensions $\left(6 \mathrm{cm}\times 4 \mathrm{cm}\right)$ and red on the surfaces of dimensions $\left(6 \mathrm{cm}\times 1\mathrm{cm}\right)$. Now, the block is divided into various smaller cubes of side $1 \mathrm{cm}$ each. The smaller cubes so obtained are separated.

How many cubes will have two sides with green colour and remaining sides without any colour?
