Answer:
2414.42 cm^2
Step-by-step explanation:
volume = base x height
and we know that a cube will always have the same length for any side so volume is basically length^3
volume = length^3
8073 = x^3
x =
use a calculator and you get that x = 20.06 cm
Surface area(SA) = 6a^2 (a is area)
a = x^2
so SA = 6(20.06)^2 = 2414.4216 ≈ 2414.42 cm^2
