The capacity of the container is 180 litres. Find the value of p.

Tunajua kuwa $1 \text{ lita} = 1000 \text{ cm}^3$.
Ujazo wa kontena ni $180 \text{ lita}$.

$$180 \text{ lita} = 180 \times 1000 \text{ cm}^3 = 180000 \text{ cm}^3$$

Ujazo $V$ wa mchemraba hutolewa na fomula:

$$V = \text{urefu} \times \text{upana} \times \text{kimo}$$

Kutoka kwenye mchoro, tuna:
Urefu $= 40 \text{ cm}$
Upana $= p \text{ cm}$
Kimo $= 50 \text{ cm}$

$$V = 40 \text{ cm} \times p \text{ cm} \times 50 \text{ cm}$$ $$V = (40 \times 50 \times p) \text{ cm}^3$$ $$V = 2000p \text{ cm}^3$$

Sasa, sawazisha ujazo huu na ujazo uliopatikana katika Hatua ya 1:

$$2000p = 180000$$

Gawanya pande zote mbili kwa 2000:

$$p = \frac{180000}{2000}$$ $$p = \frac{1800}{20}$$ $$p = \frac{180}{2}$$ $$p = 90$$

Kwa hiyo, thamani ya $p$ ni $90 \text{ cm}$.

Thamani ya $p$ ni:
