Oblicz Pc i V poniższych brył platońskich
- czworościan
- sześcian
- ośmiościan
o krawędzi a=4
Pozdrawiam, Adam
czworościan:
a = 4
Pc = a²√3
Pc = 4²√3
Pc = 16√3
V = (a³√2) / 12
V = (4³√2) / 12
V = 64√2 / 12
V = 16√2 / 3
sześcian:
Pc = 6 * a²
Pc = 6 * 4²
Pc = 6 * 16
Pc = 96
V = a³
V = 4³
V = 64
ośmiościan:
Pc = 2√3 * a²
Pc = 2√3 * 4²
Pc = 2√3 * 16
Pc = 32√3
V = (a³ * √2) / 3
V = (4³ * √2) / 3
V = (64√2) / 3
