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 \[xy=12,\]\[yz=20,\]\[zx=15\] \[\therefore \] \[{{x}^{2}}{{y}^{2}}{{z}^{2}}=12\times 20\times 15=3600c{{m}^{6}}\] \[\therefore \] \[V=xyz=\sqrt{3200}=60c{{m}^{3}}\]You need to login to perform this action.
