A) 3000
B) 100
C) 80
D) 60
Correct Answer: D
Solution :
If the length, breadth and height of the cuboid be x, y and z cm respectively, then xy = 12, yz = 20, zx = 15 \[\therefore \] \[{{x}^{2}}{{y}^{2}}{{z}^{2}}=12\times 20\times 15\] \[=3600\,c{{m}^{6}}\] \[\therefore \] \[V=xyz=\sqrt{3600}=60\,c{{m}^{3}}\]You need to login to perform this action.
