Question

Volume of the above Rubik's cube is cu units.

• A. 54
• B. 18
• C. 25
• D. 27

Answer 1

The correct option is D 27

Total no. of unit cubes in the base layer
= No. of unit cubes along the length $\times$
No. of unit cubes along the width
= 3 $\times$ 3
= 9

No. of such layers in the cube = 3

Total number of unit cubes
= No. of unit cubes in the base layer $\times$
No. of such layers
= 9 $\times$3
= 27

$\therefore$ Volume of the given Rubik's cube
= 27 cu units
