Answer: 10 cm
Step-by-step explanation:
Given: The volume of a solid piece of an aluminium cylindrical rod =[tex]200\cm^3[/tex]
The base area of cylinder = [tex]20\ cm^2[tex]
We know that the volume of cylinder is given by :-
[tex]\text{Volume]=\text{base area}\times \text{height}\\\\\Rightarrow200\=20\\times h\\\\\Rightarrow\ h=\frac{200}{20}=10[/tex]
Hence, the length of the piece of aluminium rod = 10 cm
