a)
Latura =L
Arie patrat=L*L
L=radical (16)=4 metri
volum cub=L*L*L
Volum Rezervor=4*4*4=16*4=64 metri cubi
b)
1 metru cub = 1000 litri
64*1000=64000 litri
1.45*64000=92800 dolari
c)
25/100=1/4
1/4*92800=23200 dolari
d)
masina consuma 6.4 litri in 100 km
320/100=3.2
6.4*3.2=20.48 litri (consumati in 320 km)
4/5 *40=160/5=31 l (atata are rezervorul )
31-20.48=10.52 litri ramasi
Sper ca te ajuta
Dupa consum pot sa iti zic si ce masina ar putea fi. :))
