A rectangular tank 50 cm long, 40 cm wide and 35 cm high, contains 30 litres of liquid.
:
1)Find the height of the liquid in the tank
Change 30 liters to cu/cm: 1000 * 30 = 30000 cu/cm
50 * 40 * h = 30000
2000h = 30000
h =
h = 15 cm high

2) 15000 drops of the liquid are added to the tank.
The volume of each drop of liquid is 0.4cm cube.
Calculate the new height of the liquid in the tank.
find the volume of the 15000 drops
15000 *.4 = 6000 cu/cm
Find the total volume of the liquid now
30000 + 6000 = 36000
Find the new height
50 * 40 * h = 36000
2000h = 36000
h = 36000/2000
h = 18 cm high now
