    The areas of three consecutive faces of a cuboid are \[12\text{ }c{{m}^{2}},\]\[20\text{ }c{{m}^{2}}\] and \[15\text{ }c{{m}^{2}},\] then the volume (in\[c{{m}^{3}}\]) of the cuboid is

    A)  3000

    B)  100  

    C)  80

    D)  60

    Correct Answer: C

    Solution :

    [c] If the length, breadth and height of the cuboid be x, y and z cm respectively, then \[xy=12,\]\[yz=20,\]\[zx=15\] \[\therefore \] \[{{x}^{2}}{{y}^{2}}{{z}^{2}}=12\times 20\times 15=3600c{{m}^{6}}\] \[\therefore \] \[V=xyz=\sqrt{3200}=60c{{m}^{3}}\]
