Oblicz pole powierzchni całkowitej i objętość narysowanego ostrosłupa.
H^2 + x^2 = h^2
4^2 + x^2 = 6^2
16 + x^2 = 64 - 16
x^2 = 48
x= 4√3
a=2x
a=8√3
Pc = Pp + Pb
Pp= a^2
Pp = (8√3)^2
Pp = 192 [j^2]
Pb = 4 * a*h
Pb= 4* 8√3 * 6
Pb = 192 √3 [j^2]
Pc = ( 192 + 192√3 ) [j^2]
V= Pp* H
V = 192 * 4 = 768 [j^3]
^2 - potega drugiego stopnia
[j^2) - jednostki kwadratowe
