B3. Jure has built a pool, 5 m long, 3.5 m wide, and 60 cm deep.

a) Is 10,000 liters of water enough to fill the pool?

b) How many liters of water would spill over the edge if he poured 12 m³ of water into the pool?

c) He decided to fill the pool. How much will he pay if 500 liters of water cost 200 tolars?
B3. It is best to express the length, width, and height of the pool in decimeters. Thus, $V=50 \cdot 35 \cdot 6=10500 \mathrm{dm}^{3}=10500 \ell$ and therefore $10000 \ell$ of water is not enough to fill the pool.

If $12 \mathrm{~m}^{3}=12000 \ell$ were poured into the pool, $12000-10500=1500 \ell$ of water would spill over the edge. Since $500 \ell$ of water costs 200 SIT, we first calculate $10500: 500=21$, and then determine that Jure will pay $21 \cdot 200=4200$ SIT.

Scoring: Total: 5 points

a) Calculation, e.g., $V=50 \cdot 35 \cdot 6=10500 \mathrm{dm}^{3}=10500 \ell \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots$

Answer, e.g., With $10000 \ell$ of water, the pool will not be full. .................................... 1 p

b) $1500 \ell$ of water would spill over the edge. ....................................................................... 1 p

c) Calculation, e.g., $10500: 500=21$ and $21 \cdot 200=4200$ SIT $\ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots$

Answer, e.g., Jure will pay 4200 SIT. .................................................................
