Répondre:

6 cm

Explication étape par étape:

Volume du parallélépipède rectangle V = l²h

l est la longueur du carré basé

h est la hauteur

Étant donné

V = 252 cm³

h = 7 cm

Remplacer

252 = l² (7)

252 = 7l²

l² = 252/7

l² = 36

l = √36

l = 6 cm

D'où la longueur du côté de la base carrée est de 6 cm
