If the ratio of the lengths of corresponding parts in two similar solids is 51, then the ratio of their surface areas is the square of the ratio of their lengths. Therefore, the ratio of their surface areas is ( 51^2 = 2601 ).
The statement is true.
If two solids are similar, the ratio of their surface areas is the square of the ratio of their corresponding lengths. Given that the ratio of the lengths of their edges is 29, the ratio of their surface areas is (29^2), which equals 841. Thus, the ratio of their surface areas is 841:1.

If two solids are similar and the ratio of their edge lengths is ( \frac{2}{9} ), the ratio of their surface areas is the square of the ratio of their corresponding lengths. Therefore, the ratio of their surface areas is ( \left(\frac{2}{9}\right)^2 = \frac{4}{81} ).
