If a tank of water has a 300 cm^3 area (it is 20.0 cm long and 15.0 cm wide), if it has a volume of 1.20 x 10^4 cm^3, what is its height in meters? Also, what is the capacity in liters of the tank? Also, how many kilograms of water at 4 degrees C will the tank hold?

thank you all

the lacunae
area cannot be 300 cm^3
the poblem is incomplete

If a tank of water has a 300 cm^3 area (it is 20.0 cm long and 15.0 cm wide), if it has a volume of 1.20 x 10^4 cm^3, what is its height in meters? Also, what is the capacity in liters of the tank? Also, how many kilograms of water at 4 degrees C will the tank hold?
the area of x-section=300cm^2
the volume=12000cc
so capacity in litres=12l
height=volume/area
=12000/300=40 cm
=0.4 m
the kgs it will hold will be 12 at 4*C

(1)
Volume = Area * height
→ height = Volume / Area
Height = [1∙2* 10^4 cm^3]/ 300cm²
Height = 40 cm.
(2)
Volume = 1∙2* 10^4 cm^3
But 1000cm^3 = 1 Liter.
Number of Liters = 1∙2* 10^4 cm^3 / 1000cm^3
Number of Liters = 12 Liters.
(3)
Maximum density of water is at 4ºC. Pure water has a mass of 1Kg per Liter.
1 Liter = 1 Kg.
12 Liter = 12 Kg.

revise it looks like it is a 2 gal tank. beta is a good solo fish & there some very beautiful colors out there that you could display in a tank that size. --------------------------------------... I am guessing that it is a 5 gallon tank. I learned this the hard way that you should only have 1" of fish per gallon, which is just an estimate, because you also have to factor in the filter, gravel & maybe a plant that takes up space & breathing room. Danios are small I would go 3 or 4 maybe pushing it if it is a small tank, & be careful if the pet store trys to sell you more. Also remember if you have a filter, it keeps the water clean, but does not mean you can have a large amount of fish in there. Have fun & good luck

height in cm 1.2x 10^4/300 = 400cm = 4m
Capacity in liters 1L = 10^3 cm^3 so 1.2 * 10^4 /1000 = 12 L
1L = 1 kg so weight = 12 kg

for height, take the volume divided by area. 1liter=1000cm3 , so capacity in liters is 12. for weight of water, look up density of water at 4 degrees C. multiply the density by 12

2 plus 2 equals 4. Now you have the basic's the rest should be no problem

Sounds like your math professor sucks . Just let your professor put his hand on your a.ss like the guy in your 360 picture and you will get a 4.0 for the semester
