Answer:
Option (D) 10 cubes
Step-by-step explanation:
The given structure is formed by assembling the cubes.
Number of cubes required for upper layer of the structure = 7 cubes
Now we have to find how many cubes will be required to form the lower layer of the structure.
From the structure ⇒
Cubes in lower layer = cubes in upper layer + 3 more cubes
= 7 + 3 = 10 cubes
Therefore, 10 cubes will be required to form the base of the structure.
Option (D) 10 cubes is the answer.
