Szczegółowe wyjaśnienie:
Pc¹
16² = 256
8²+h²=20²
h²=400-64
h²= 336
h = 4√21
Pb = 4× [(16×4√21):2]
Pb = 32√21
Pc¹ = 32√21 + 256
Pc²
Pp = 6×[(4²√3):2]
Pp = 48√3
h²+2²=9²
h²= 81-4
h²= 77 /:√
h =√77
Pb = 6×[(√77×4):2]
Pb = 12√77
Pc² = 12√77 + 48√3
Pc³
Pp = (30×30):2
Pp = 450
15²+h²=25²
h²= 625-225
h=√400
h= 20
Pb = 3×[(30×20):2]
Pb = 900
Pc³ = 450+900
Pc³ = 1350
