Vpir = Ab·h/3 = l²·h/3 = 16²·6/3 = 256·6/3 = 512 cm³
Vpir = V pat = 512 = Lpat³
Lpat = ∛512 = ∛8³ = 8 cm
Vpir = V pat = 512 = Lpat³
Lpat = ∛512 = ∛8³ = 8 cm
[tex]\it \mathcal{V}_p = \dfrac{\mathcal{A}_b\cdot h}{3} = \dfrac{16^2\cdot6}{3} = 16^2\cdot2 = (2^4)^2\cdot2= 2^9=(2^3)^3=8^3 \\ \\ \\ \mathcal{V}_{cub} = a^3=8^3 \Longrightarrow a=8\ cm\ (muchia\ cubului)[/tex]
