MULTE PUNCTE!!!

Un acvariu sub forma de paralelipiped dreptunghic cu dimensiunile de 31 cm, 25 cm si 50,5 cm (inaltimea) are grosimea sticlei de 5mm. Cati litri de apa incap in acvariu?

Answer 1

5mm=0,5cm

V=L*l*h= 31*25*50,5=  39137,5cm³

V=l*L*h
l=L=h=0,5

V=(0,5)³= 0,125cm³

39 137,5 -0,125= 39 137,375cm³  este volumul apei

39 137,375cm³= 39, 137 375dm³ = 39, 137 375l incap in acvariu
