2) Un acvariu are dimensiunile de : lungimea 10 cm ,latimea 50 cm si inaltimea de 60 cm.Calculeazacati litri de apa intra in acvariu ?

Answer 1

1)$v= \frac{d}{t}= \frac{185,7}{3,095}=60km/h$
2) $V=L\cdot l\cdot h=10\cdot 50\cdot 60=30000 cm^{3} =30 dm^{3}=30 l$

Answer 2

1.185,7 km:3,095 ore=60KM|ora
2. V =L*l*i=10cm*50cm*60cm=30000 cm la 3 =30 l
