Answer:
Step-by-step explanation:
Find the area of the cuboid--> 90 x 75 = 6,750 cm^2
Multiply that by 1 cm to get volume with height at 2 cm --> 6750 x 1 = 6,750cm^3
Calculate how many liters flow in 12 minutes --> 7 x12 = 84 liters
84 liters = 84,000 cm^3
divide 84,000 by 6750 = 12.4444
height = 12.44 cm
