a. Answer: [tex]\bold{2\sqrt[3]{10}}[/tex]
Step-by-step explanation:
V = s³ and V = 80
⇒ s³ = 80
[tex]\sqrt[3]{s^3} =\sqrt[3]{80}\\\\s=\sqrt[3]{8\cdot 10}\\\\s=2\sqrt[3]{10}[/tex]

b. Answer: [tex]\bold{24\sqrt[3]{100}}[/tex]
Step-by-step explanation:
S = 6s²
[tex].\quad =6(2\sqrt[3]{10})^{2}\\\\.\quad =6\cdot 2\cdot 2\sqrt[3]{10^2}\\\\.\quad =24\sqrt[3]{100}[/tex]
