a)
a = 8 cm
H = 15 cm
Pp = a^2 pierwiastków z 3 / 4
Pp = 8^2 pierwiastków z 3 / 4
Pp = 64 pierwiastków z 3 / 4
Pp = 16 pierwiastków z 3
V = 1/3 * Pp * H
V = 1/3 * 16 pierwiastków z 3 * 15
V = 5 * 16 pierwiastków z 3
V = 80 pierwiastków z 3
b)
a = 8 cm
H = 15 cm
Pp = a^2
Pp = 8^2
Pp = 64
V = 1/3 * Pp * H
V = 1/3 * 64 * 15
Pp = 5 * 64
Pp = 320
