Count the number of Cubes in each of the following figures :
|
|
A. 68 |
B. 69 |
|
C. 70 |
D. 71 |
Ans : B. In figure, there are 11 columns containing 4 cubes each, 7 columns containing 3 cubes each and 2 columns containing 2 cubes each. Therefore Total number of cubes = (11×4) + ( 7×3) + (2 ×2) = 44 + 21 + 4 = 69.

7. |
Count the number of Cubes in each of the following figures :
|
|
A. 25 |
B. 27 |
|
C. 30 |
D. 35 |
Ans : C. In figure, there are 1 columns containing 3 cubes, 7 columns containing 2 cubes each and 13 columns containing 1 cubes each. Therefore Total number of cubes = (1×3) + ( 7×2) + (13 ×1) = 3 + 14 + 13 = 30.

8. |
Count the number of Cubes in each of the following figures :
|
|
A. 6 |
B. 8 |
|
C. 10
|
D. 12
|
9. |
Ans : C.Clearly, there are 1
column containing 3 cubes, 2 columns containing 2 cubes each and each 3
columns containing 1 cube each. Hence, there are ( 1×3) + (
(2×2) + ( 3×1) = 3 + 4 + 3 = 10.
Count the number of Cubes in each of the following figures :
|
|
A. 144 |
B. 150 |
|
C. 158 |
D. 168 |
10. |
Ans : D. In the figure, there are 48 columns containing 4 cubes each and 12 columns containing 2 cubes each. Total number of cubes = (48 ×3) + ( 12 ×2) = 144 + 24 = 168.
Count the number of blocks in the given figure :
|
|
A. 6 B. 7 |
|
|
C. 8 D. 9
Ans : B. There are 4 blocks in the lower layer close to the ground. Also, there are 3 blocks standing over the lower layer of blocks. Thus, there are 4 + 3 = 7 blocks in the given figure.
