Solution:

Keep in Mind, when two shapes or polygons are similar , the ratio of their areas is equal to square of their corresponding sides or edges.

As given, Ratio of the edges of two solids = [tex]\frac{4}{5}[/tex]

Ratio of their Surface areas

= ( Ratio of the edges of two solids)²=[tex](\frac{4}{5})^2[/tex]

=[tex]\frac{16}{25}[/tex]

Option A: 16: 25 is true.
