The fish tank is 48CM long, 40cm high and 25cm wide. The volume of the rockery in the fish tank is 4400 cubic centimeters, and the flow rate of the water pipe is 8 cubic decimeters per minute What is the height of the rockery in centimeters?

The fish tank is 48CM long, 40cm high and 25cm wide. The volume of the rockery in the fish tank is 4400 cubic centimeters, and the flow rate of the water pipe is 8 cubic decimeters per minute What is the height of the rockery in centimeters?

48*40*25=48000
48000-4400=43600
8 cubic decimeters per minute = 8000 cubic centimeters per minute
43600 / 8000 = 109 / 20 minutes

A glass jar is 1.2 meters long, 0.4 meters wide, 0.8 meters high and 0.5 meters deep. It is immersed in a rockery with a volume of 96 cubic decimeters, a few decimeters away from the mouth of the jar

8-5-96 (12 × 4) = 3-2 = 1 (decimeter)
A: the water surface is 1 decimeter away from the cylinder mouth

There is some water in a rectangular glass fiber reinforced plastic. The distance on the water surface is 0.6 decimeters, 10 decimeters long and 8 decimeters wide. We are going to put 60 cubic decimeters of rockery in the tank
Will the water overflow? If so, how many cubic decimeters?

10 * 8 * 0.6 = 48 cubic decimeter
The volume of rockery is 60 cubic decimeter > 48 cubic decimeter
So the water will overflow
Overflow 60-48 = 12 cubic decimeters
