a) V = 1/3*72cm2*24 = 24cm2*24cm=576cm3
b)V = 1/3*150cm2*40cm(4dm) = 50cm2*40cm=2000cm3
c)V = 1/3*270cm2*80cm=90cm2*80=7200cm3

a) Pp: 80cm2
V=200cm3
wzor na V ostrosłupa:
V=1/3Pp*h
200cm3 = 1/3*80cm2 *h
200cm3-80cm2*1/3 = h
120cm*1/3=h
h=40cm
b)h=99cm
V=660cm3
660cm3=1/3Pp*99cm
660cm3 - 99cm = 1/3Pp
561cm2=1/3Pp
Pp: 187cm2
Jezeli potrzebujesz moge namalowac w paincie dokladnie.
