Volume of copper should be #3.333# #cm.^3#

As weight is volume multiplied by density of an object,

weight of lead is #2.62xx11.4# #g.#

Let the volume of copper be #V_c#

its weight would be #V_cxx8.96# and as it is equal to weight of lead

#V_cxx8.96=2.62xx11.4#

or #V_c=(2.62xx11.4)/8.96=29.868/8.96=3.333# #cm.^3#
