The dimensions of a typical front yard are 25 meters wide by 10 meters long, and 30% of that area is covered in concrete, for a driveway. Assume that any water that lands on the concrete will be runoff that will not infiltrate the ground. ​

A

$2000 \ cm^{3}$

B

$14 \ m^{3}$

C

$7.5 \ m^{3}$

D

$2000 \ m^{3}$

E
