Raspuns : a) volum cub = 64 000 cm³
b) inaltime paralelipiped = 4 dm
Volumul cubului = Volumul paralelipipedului
Muchia cubului = 4 dm = 4 x 10 = 40 cm
Volum cub = Muchia x muchia x muchia = 40 cm x 40 cm x 40 cm = 64000 cm³
Volum Paralelipiped = Lungime x latime x inaltime
Inaltimea = Volum : (Lungime x latime)
Volum paralelipiped = volum cub = 64000 cm³
Lungime = 80 cm
latime = 20 cm
inaltime = 64000 cm³ : ( 80 cm x 20 cm ) = 64000 cm³ : 1600 cm² = 40 cm = 4 dm
[ 1 dm = 10 cm ]
