a)
Pc = 2Pp + Pb = 2a^2 + 4aH
Pp = a^2
a = 5 cm
Pp = 25 cm^2
Pb = a * H
H = 2a = 10 cm
Pb = 5 * 10 = 50 cm
Pc = 2Pp + Pb = 2a^2 + 4aH
Pc = 2 * 25 + 4 * 50 = 50 + 200 = 250 cm^2
V = a^2 * H
V = 5^2 * 10 = 25 * 10 = 250 cm^3
b) nie wiem sorka :(
c) | - pierwiastek
Pc = 2Pp + Pb
a = 12 cm
H = a/3 = 4 cm
Pp = (a^2 |3)/4
Pp = (12^2 |3)/4 = (144 |3)/4 = 36 |3
Pb = a * H
Pb = 12 * 4 = 48 cm^2
Pc = 2Pp + Pb
Pc = 2* 36 |3 + 3 * 48 = 144 + 72 |3
V = Pp * H
V = 36 |3 * 4 = 144 |3
