Question

determine a medida da aresta de cada cubo a parti do seu volume a) v= 125 b) v= 729 c) v= 1728 d) v= 3375

Answer 1

³V(125)  = ³V5³ = 5 ****

³V(729) =  ³V3³ * ³V3³ =  3 * 3 = 9 ****

³V(1728) = ³V2³ * ³V2³ * ³V3³ =  2 * 2 * 3 = 12 ****

³V3375 =³V3³ * ³V5³  = 3 * 5 = 15 ***

Answer 2

a)   a = 5
b)   a = 9
c)   a = 12
d)   a = 15
