# The areas of three adjacent faces of a cuboid are a, b and c sq. m. Its volume will be :

- abc m
^{3} - √(a
^{2}+b^{2}+c^{2}m^{3}) - √abc m
^{3} - 3√abc m
^{3}

**Answer: (3) √abc m³**

**Explanation:-**

Let the edges be X, Y and Z

Then, square of X = a,

square of Y = b,

square of X = c

Then, the volume of the cuboid = X Y Z = (**√**a ) (**√**b) **√**c)

= **√**abc

Hence, the answer is (3)**√**abc m**³**.
