5dm * 3dm * 6dm = 90 dm(szesciennych)
90dm(szesciennych)=90l
2. H=15cm
Pp = 28
V=Pp*H V=28*15 V=420cm(szesciennych)
3. 3dm = 30 cm 1,2dm = 12 cm
V=A*B*H V=5760cm(szesciennych)
b=30cm
c=6dm=60cm
P=abc=50*30*60=9000cm³=9dm³
3)
a- 16cm
b- 1,2 dm=12cm
H- 3 dm=30cm
P=abc=16*12*30=5760cm³=5,76dm³
2)
P=Pp*h
h=15cm
Pp=28cm²
P=15*28=420cm³
a=5dm
b=30cm=3dm
c=6dm
V=pp*h
V=5dm*3dm*6dm=90dm(szesciennych)=9l
Odp to tego akwarium mozna wlac 9 litrow wody
2 V=pp*h
V= 28cm(kwadrat) * 15 cm = 420 cm (szescienncyh)
3
1,2dm=12cm 3dm=30cm
V + pp*h
V=16cm*12cm*30cm=5760cm(szesciennych)
