calculati lungimea laturii unui cub care are volumul egal cu
a 8 cm (cub)
b 27 dm (cub)
c 64 m (cub)
d 1000 hm(cub)
e 216 dam (cub)
f 0.001 dm (cub)
va rog frumos


Răspuns :

V=l^3
a) 8=2^3
l^3=2^3
l=2 cm

b)27=3^3
l^3=3^3
l=3 dm

c) 64=4^3
l^3=4^3
l=4 m

d) 1000=10^3
l^3=10^3
l=10 hm

e) 216=6^3
l^3=6^3
l=6 dam

f) 0.001 dm=1/1000
l^3=1/10^3
l=1/10 dm
