B) 4 cm
C) 3.5 cm
D) 3 cm
Correct Answer: A
Solution :
Edge of cube = 9 cm For rectangular vessel Length = 15 cm. Breadth = 12 cm Let the rise in the water level is x cm Volume of cube \[={{9}^{3}}=9\times 9\times 9\] Volume of vessel \[=15\times 12\times x\] \[\Rightarrow \] \[15\times 12\times x=9\times 9\times 9\] \[x=\frac{9\times 9\times 9}{15\times 12}=\frac{81}{20}=4.05\,\,\text{cm}\]You need to login to perform this action.
