in 6 minutes the first tap will fill (12)(6) or 72 L

in the same 6 minutes the 2nd tap will fill (9)(6) or 54 L

for a total of 126 L

This is equal to 126 000 cm^3 (ahh, the beauty of the metric system)

volume of tank = area of base x height

= 2400h

= 126000

h = 52.5 cm

B)

During our 6 minutes we lost (2)(6) or 12 L

or 12000 cm^3

so 2400h = 126000 - 12000

h = 47.5 cm
