Odpowiedź:
2*(2 x + 3 x ) = 10 x = 50
x = 5
a = 2 x = 10 b = 3 x = 15
-----------------------------------------
[tex]a^2 + b^2 + h^2 = 20^2[/tex]
10² + 15² + h² = 400
100 + 225 + h² = 400
h² = 75 = 25*3
h = [tex]\sqrt{25*3} = 5\sqrt{3}[/tex]
------------------------------
Pc = 2*(a*b + a*h + b*h ) = 2* ( 10*15 + 10*5[tex]\sqrt{3}[/tex] + 15*[tex]5\sqrt{3}[/tex] )
Pc = 300 + 250√3 j²
=======================
V = Pp*h = a*b*h = 10*15*5√3 = 750 √3 j³
