zadanie 5
a)
[tex]9^{2}[/tex] + [tex]h^{2}[/tex]= [tex]5^{2}[/tex]
[tex]h^{2}[/tex] = [tex]\sqrt{25 - 9}[/tex]
h = 4
V = 2 * Pp * H = 2 * [tex]\frac{(12 + 6) * 4}{2}[/tex] * 5 = 2 * [tex]\frac{36}{2}[/tex] * 5 = 180[tex]cm^{2}[/tex]
b)
V = 2 * Pp * H = 2 * [tex]\frac{(8 + 4) * 4}{2}[/tex] * 6 = 2 * 24 * 5 = 240[tex]cm^{2}[/tex]
zadanie 6
a)
Pc = Pp + Pb = 2 * (8 * 4) + [tex]\frac{4\sqrt{3} }{2}[/tex] * 3 = 64 + 6[tex]\sqrt{3}[/tex]
b)
Pc = Pp + Pb = 2 * ([tex]\frac{6 * 5}{2}[/tex]) + 6 * 5 + (6 * 13) * 2 = 30 + 30 + 156 = 216
