Question

exprimati in cm cubii volumul unui paralelipiped dreptunghic ce are dimensiunile : 

a) L=12 cm   l-30mm h-0,8 dm
b) L-6,5       l-40 mm     l-0,1 dm

Answer 1

a)L=12cm
l=30mm=>3cm
h=0,8dm=>8cm
V paralelipipedului dreptunghic=L*l*h
V=12*3*8=288cm cubi

Answer 2

a)12cm=0,12m
30mm=0,03m
0,8dm=8m

V=0,12*0,03*8=0,0288m³

b)6,5cm=0,065m
40mm=0,04m
0,1dm=1m

V=0,065*0,04*1=0,0026m³
