Swimming pool

The swimming pool has the shape of a block with dimensions of 70dm, 25m, 200cm. How many hl of water can fit into the pool?

Correct result:

V =  3500 hl

Solution:

a=70 dm→m=70/10 m=7 m b=25 m c=200 cm→m=200/100 m=2 m  V1=a⋅ b⋅ c=7⋅ 25⋅ 2=350 m3 V=V1→hl=V1⋅ 10 hl=350⋅ 10 hl=3500 hl=3500 hla=70 \ dm \rightarrow m=70 / 10 \ m=7 \ m \ \\ b=25 \ \text{m} \ \\ c=200 \ cm \rightarrow m=200 / 100 \ m=2 \ m \ \\ \ \\ V_{1}=a \cdot \ b \cdot \ c=7 \cdot \ 25 \cdot \ 2=350 \ \text{m}^3 \ \\ V=V_{1} \rightarrow hl=V_{1} \cdot \ 10 \ hl=350 \cdot \ 10 \ hl=3500 \ hl=3500 \ \text{hl}
