Question

. A student was given two metal cubes that looked similar. One was 1.05 cm on an edge and had a mass of 14.32 grams; the other was 2.66 cm on a side and had a mass of 215.3 grams. Determine whether these two cubes of metal are the same material using only the data given. 

Answer 1

Density, $D= m/v$

D1= 14.32/1.05³

=14.32/1.16 =12.34g/cm³

D2= 215.3/2.66³

=215.3/18.82 =11.44g/cm³

The cubes are not of the same material
