How Many Cubes are There in The Given Figure

Introduction:

You may have come across many shapes in your life. When the shape is drawn on a piece of paper, it is a two-dimensional shape. But a three-dimensional (3-D) figure is a solid shape with length, width, and height. A cube is such a 3-D regular figure.

Cubes:

Cubes are regular objects with six faces, twelve edges, and eight vertices. It is also called a regular hexahedron. The length of all sides is equal and all the faces are identical. Thus it is called a regular body. Their faces are square-shaped and also, and all of their diagonals are equal. And all the faces of the cube meet at right angles. We come across cubic shapes in our daily lives such as Rubix cubes, cheese cubes, ice cubes, etc.

Questions about cubes and cubic shapes are seen in many competitive exams which have to be solved with our logic.

Let us look at some examples.

Examples:

• Calculate the total number of cubes in the given picture.

In the given figure, the lowest layer contains 6 cubes, of which only 3 are seen.

In the middle layer, there are 3 cubes ( we can see only 2 and so 1 is hidden), and the topmost layer has 1 cube.

So in total, there are 6+3+1=10 cubes in this picture.

• How many cubes are there in the given picture?

In the given figure, the lowest layer contains 3 cubes.

The topmost layer has 1 cube.

So in total, there are 3+1=4 cubes in this picture.

• How many cubes are in the below image

In the given figure, the lowest layer contains 4 cubes.

The third layer from the top contains 3 cubes, and the second layer has two cubes. and the topmost layer has 1 cube.

So in total, there are 4+3+2+1=10 cubes in this picture.

• Calculate the total number of cubes present in the given image.

In the given image there are 10 cubes

in the same line. And the total number of cubes in the image is also 10

• What is the total number of cubes in the below image?

In the given image there are 2 different lines present in the image.

In the first line, there are 10 cubes.

And the cubes in the second line are also 10.

The total number of cubes in the given image is 10+10=20

Conclusion :

In these types of queries about logical reasoning, they tend to evaluate your level of thinking and the way of answering such questions. You must deduce the accurate answer based on the details provided. In these above questions about cubes, you can only see a few cubes but for other remaining cubes you have to visualize them.
