Question

the density of an object is given by the quotient of its mass and its volume. if a copper cube has a side of 2cm and a mass 71.68g,find its density in g/cm

Answer 1

Volume =2cm×2cm×2cm=8cm
Mass=7168÷100
As,we know that
DENSITY=MASS÷VOLUME
DENSITY=7168÷100÷8
=7168 = 7168
--------- = ---------- = 8.96gcc
100×8 = 800
Density=8.96cc
