Question

There is a cuboid whose dimensions are 4 x 3 x 3 cm. the opposite faces of dimensions 4 x 3 are coloured yellow. the opposite faces of other dimensions 4 x 3 are coloured red. the opposite faces of dimensions 3 x 3 are coloured green. now the cuboid is cut into small cubes of side 1 cm. how many small cubes are there which have only red color on them?

Answer 1

Answer:

There are total 4 cubes with only red color on them.

Step-by-step explanation:

We are given that,

The dimensions of the cuboid are 4 × 3 × 3 cm.

Further, we have,

The faces of dimensions 4 × 3 cm are colored yellow.

The faces of dimensions 4 × 3 cm are colored red.

The faces of dimensions 3 × 3 cm are colored green.

Now, small cubes of 1 cm are cut from the cuboid as shown in the figure below.

It is required to find the number of cubes with only red color.

So, we get that,

The number of cubes with only red color = 2 in the middle row from top + 2 in the middle row from the bottom.

Thus, there are total 4 cubes with only red color on them.
