A cuboid having the surface area of 3 adjacent faces as a, b, c has the volume:
\( a^{3}b^{3}c^{3} \)
\( (abc)^{\frac{1}{3}} \)
abc
\( (abc)^{\frac{1}{2}} \)

In the given figure, value of x is:
Solve the following.
\( \left(1+4-\frac{42}{14}+65\right)+\left(\frac{2+7\times9}{13}\right)\times(65+7-19)+(19-25\times15) = \) ?
