2% ok bro please mark as brainliest

Answer 2

$\huge\bold{\mathtt{\purple{ A{\pink{ N{\green{ S{\blue{ W{\red{ E{\orange{ R}}}}}}}}}}}}}$

Sɑ of the cube = 6ɑ²

now if ɑ = $\frac{a}{2}$

new SA = $6 (\frac{a}{2} )^{2} = \frac{6}{4} {a}^{2}$

Rɑtio of new/old = $\frac{\frac{6}{4}{a}^{2}}{6 {a}^{2} }$ = $\frac{1}{4}$
