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?

Result

V =  3500 hl

Solution:

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