Question

Un vas are forma˘ de paralelipiped dreptunghic cu dimensiunile L“4dm, l “2dm ¸si h“45cm. Calcula¸ti num˘arul maxim de litri de ap˘a care pot fi turna¸ti ˆın vas.

Answer 1

45 cm=4,5 dm
V=L*l*h
V=4*2*4,5=36 dm³
1 dm³=1 l apa
36 dm³=36 l apa pot fi turnati

Answer 2

l=2dm
L=4dm
h=45cm=4,5dm
V=Lxlxh=2x4x4.5=36$dm ^{3}$
$1dm^{3}=1l$
$36dm^{3}=36l$
