Ile litrów wody pomieści to akwarium ?
Grubość szyby to 3mm
a = 39cm - 3mm = 390mm - 3mm = 387mm = 3,87dm
b = 25cm - 3mm = 250mm - 3mm = 247mm = 2,47dm
h = 25cm - 3mm = 250mm - 3mm = 247mm = 2,47dm
V = a * b * h
V = 3,87dm * 2,47dm * 2,47dm
V = 23,610483dm^3 ~ 23,6l ---- odpowiedź
a=25 cm =2,5 dm - 0,03 dm=2,47 dm
b=39 cm =3,9 dm -0,03 dm = 3,87 dm
c=25 cm=2,5 dm - 0,03 dm = 2,47 dm
V=a*b*c
= 2,47 dm * 3,87 dm * 2,47 dm =
≈23,6 dm³
1dm³=1l
więc:
odp:
ok. 23,6 l wody
