Question

Un bazin in forma de paralelipiped dreptunghic cu lungimea de 6 m si adancimea de 15 dm se umple cu 4,5 kl de apa
a) Care este latimea bazinului?
b) Cati m cub de apa cantine bazinul ?
Ajutati-ma va rog frumos

Answer 1

$6m \to 60dm \\\\ 4,5kl \to 4500 l \\\\ \boxed{1dm^3=1l} \\\\ V_{apa}= 4500l \to 4500 dm^3 \\\\ b) V_{apa}=4500dm^3 \to \boxed{ 4,5 m^3 } \\\\\\ a)V=L*l*h \\\\ 4500dm^3=60dm*15dm*l \\\\ 4500dm^3=900dm^2 * l \\\\ l= \frac{\not 4500dm^ {\not3}}{\not 900dm^ {\not 2}} \\\\ \boxed{l=5 dm}$

Answer 2

L=6m
h=15 dm=1,5 m
b)V=4,5 kl=4500 l=4,5 m³
a)V=L*l*h⇒
  l=4,5:(1,5*6)=4,5:9=0.5 m
