Quả cầu nằm cân bằng trong nước nên: \(F_A=P\)

\(\Rightarrow d\cdot V=10m=10\cdot0,085=0,85N\)

Mặt khác: \(V=2\cdot S\cdot h\Rightarrow d\cdot2\cdot S\cdot h=0,85\)

\(\Rightarrow S=\dfrac{0,85}{2\cdot d\cdot h}=\dfrac{0,85}{2\cdot10000\cdot34\cdot10^{-3}}=1,25\cdot10^{-3}m^2=12,5cm^2\)

\(m=\sqrt[3]{6}\)

`m^3=6`

`to m=\(\sqrt[3]{6}\)

căn bậc 3 của 6

-m+6m=-180+540

5m=360

m=360:5
