Question

1.Calculeaza volumul cubului :
a) cu latura de : 2 m ; 10 cm ; 1,2 dm ;
2. Calculeaza latura unui cub :
a) cu volumul de 27 cm cubi ; 64 m cubi ; 125 mm cubi.

Answer 1

1.l=2m
V=l*l*l=2*2*2=8m cubi
l=10cm
V=l*l*l=10*10*10=1000cm cubi
l=1,2dm
V=l*l*l=1,2*1,2*1,2=1,728dm cubi

2.
V=27cm cubi
l=3cm
V=64m cubi
l=4m
V=125mm cubi
l=5mm
