Graniastosłup o podstawie trapezu
a = 20
b = 10
h = 11,5
r1 ( ramię ) = 13
r2 = 12
H = 30
Pp = ( a + b ) * h / 2
Pp = ( 20j + 10j ) * 11,5j / 2
Pp = 345j² / 2 = 172,5j²
Pb = H ( a + b + r1 + r2 )
Pb = 30j ( 20j + 10j + 13j + 12j )
Pb = 600j + 300j +690j + 360j
Pb = 1950j²
Pc = 2Pp + Pb
Pc = 345j² + 1950j²
Pc = 2295 j²
Pozdrawiam! ;D
