Answer 1

Ratio of TSA : 6a^2/6a^2

=6(1)^2/6(5)^2

=1/25

ratio=1:25

Answer 2

Here is your step by step explaination:

$area \: of \: cube \: = \: 6 \times (side) {}^{2} \\ \\ area \: of \: small \: cube \: = 6 \times 1 {}^{2} = 6cm {}^{2} \\ area \: of \: big \: cube \: = \: 6 \times 5 {}^{2} = 6 \times 25 = 150cm {}^{2} \\ \\ ratio \: = \: 6/150 = 1/25 \ \\ \\ please \: mark \: it \: as \: brainliest$
