    What is the total volume of the smallest number of cubes that must be added to make the given figure a cuboid?

    A) \[104\,\,c{{m}^{3}}\]              

    B)           \[64\,\,c{{m}^{3}}\]                

    C)           \[27\,\,c{{m}^{3}}\]                

    D)           \[13\,\,c{{m}^{3}}\]                

    Correct Answer: A

    Solution :

    The given figure becomes a cuboid if it has\[4\times 3\times 2=24\] cubes. The no. of cubes in the given figure\[=11\] \[\therefore \]The no. of cubes that must be added to make it a cuboid\[=24-11=13\] Hence, its volume\[=13\times 2\times 2\times 2\,\,c{{m}^{3}}\] \[=104\,\,c{{m}^{3}}\]
