A) 5 m
B) 4 m
C) 4.5 m
D) 6 m
Correct Answer: B
Solution :
Let the width of a wall \[=x\,m\] \[\therefore \] The height of a wall \[=6x\,m,\] and length of a wall \[=42x\,m\] Volume of a wall \[=\text{ }42x\times 6x\times x\] \[\Rightarrow \] \[{{x}^{3}}=\frac{16128}{42\times 6}\] \[\Rightarrow \] \[{{x}^{3}}=64\] \[\Rightarrow \] \[x=4\] \[\therefore \] The width of the wall \[=4\,m\]You need to login to perform this action.
