Explanation : From the given figure, it consists of 1 column containing 3 cubes and 2 columns containing 2 cubes each and 3 columns containing 1 cubes each.Number of cubes in columns of 3 cubes = 1 x 3 = 3.Number of cubes in columns of 2 cubes = 2 x 2 = 4.Number of cubes in columns of 1 cubes = 3 x 1 = 3.Therefore, total number of cubes = 3 + 4 + 3 = 10.

Example : Find the number of cubes in the given figure.

A.  15

B. 16

C. 17

D. 14
