Question

· A measuring cylinder contains water to a
level of 22 mL. The water level rises to
30 mL when a piece of copper is
completely immersed in it. Find the
volume of copper piece in (a) cm3 (b) m3.

Answer 1

Answer:

Given : Initial level of water V1 = 22 mL

Final level of water V2 = 30 mL

(a) Volume of copper piece V=V2−V1

= 30 mL - 22 mL = 8 mL

Since 1 mL = 1cm3,V=8cm3

(b) Since 1cm3=10−6m3

Volume of copper piece = 8×10−6m3
