[tex]cm^{2}[/tex]Odpowiedź:
V = 1/3 * 144 * 18 = 864 cm^3
Pc = 144 + 144[tex]\sqrt{10}[/tex] = 144(1+[tex]\sqrt{10}[/tex])[tex]cm^{2}[/tex]
Szczegółowe wyjaśnienie:
Pc = Pp + Pb
Pp = 12 * 12 = 144 (cm2)
Pb = 4 * 12*h / 2
h^2 = 18^2 + 6^2
h^2 = 324 + 36
h = [tex]\sqrt{360}[/tex] = [tex]6\sqrt{10}[/tex]
Pb = 4 * 6 * [tex]6\sqrt{10}[/tex] = 144[tex]\sqrt{10}[/tex]
Pc = 144 + 144[tex]\sqrt{10}[/tex] = 144(1+[tex]\sqrt{10}[/tex])[tex]cm^{2}[/tex]
V = 1/3 * Pp * H
V = 1/3 * 144 * 18 = 864cm^3
