Ad d-nexdem sseqf iwumi ara neg targa. Akka mi ara d-tewwet lehwa, aman-nni ad ten-id-neḥweṣ ɣer ugelmim.

{{Deg useggas, acḥal n waman i nezmer ad d-nejmeε?}}

I wakken ad nektil aya, yessefk ad neḍfer leḥsab-a:

Tasmekta n waman ara d-nejmeε = (acḥal i d-yekkaten d lgerra deg temnaṭ ideg yella ssqef ) x (tajumma n ssqef)

Amedya:

– Di tmurt n Yeqbayliyen, ageffur yetteɣlay-d s waṭas, s tlemmast n 800 mm.
– Ad d-nin ssqef-nneɣ ɣur-s 100 m².

Ihi, tasmekta n waman ara d-nejmeε deg useggas = 800 x 100 = 80 000 litra = 80 m3
