Min's fish are sick,and she wants to add medicine to the tank. The base of the fish tank measures 40 cm by 25 cm.The tank is filled with water to a height of about 20 cm.How many drops of medicine should Min add to her tank?
Reminder:1L=1,000cm squared
How many drops should she add per liter?
1 Liter = 1,000 cc (cm^3).
10
To determine the number of drops of medicine Min should add to her tank, we need to calculate the volume of the tank first.
The dimensions of the base of the fish tank are given as 40 cm by 25 cm. To find the area of the base, we multiply the length and width:
Area of base = length * width
Area of base = 40 cm * 25 cm
Area of base = 1000 cm²
Next, we need to determine the volume of the tank by multiplying the area of the base by the height of the water. The height is given as 20 cm:
Volume of tank = area of base * height
Volume of tank = 1000 cm² * 20 cm
Volume of tank = 20,000 cm³
Since 1 liter is equal to 1,000 cm³, we can convert the volume of the tank to liters:
Volume of tank in liters = volume of tank in cm³ / 1,000 cm³/L
Volume of tank in liters = 20,000 cm³ / 1,000 cm³/L
Volume of tank in liters = 20 L
Now, the number of drops of medicine to add will depend on the dosage instructions provided by the manufacturer. Usually, medicine dosages are given in terms of volume per liter. For example, it may be recommended to add 10 drops per liter.
To find the number of drops for Min's tank, we will multiply the volume of the tank in liters by the recommended dosage per liter. Let's assume the recommended dosage is 10 drops per liter:
Number of drops of medicine = Volume of tank in liters * Recommended dosage per liter
Number of drops of medicine = 20 L * 10 drops/L
Number of drops of medicine = 200 drops
Therefore, Min should add 200 drops of medicine to her fish tank. Note that the recommended dosage may vary, so it's important to check the instructions provided with the medicine for the appropriate dosage.
