• A. 9 cubic units
• B. 11 cubic units
• C. 4 cubic units

Answer 1

The correct option is B 11 cubic units

The given solid can be divided as
The unit cubes in 1st Layer = 5
The unit cubes in 2nd Layer = 4
The unit cubes in 3rd Layer = 2

Total number of unit cubes = 5 + 4 + 2 = 11
$\therefore$ The volume of the solid = 11 cubic units.
