A group of learners recorded the volume of water in a measuring cylinder as 150cm³.State whether this is a basic or derived unit. Give a reason

Hapa kuna jibu lako:

Hii ni kitengo kilichotokana (derived unit).

Sababu: Ujazo (volume) hupatikana kwa kuzidisha vitengo vya msingi vya urefu (kama vile sentimita) mara tatu ($\text{cm} \times \text{cm} \times \text{cm} = \text{cm}^3$). Kwa hivyo, si kitengo cha msingi bali kimetokana na vitengo vya msingi.
