An aqaurium is 80cm long, 40cm wide, and 40cm high. What is its volume?

I got 128,000cm3

One cubic centimeter (cm3) holds 1 milliliter of water. 1,000 cm3 hold 1 liter. How many mL will the tank in problem 6 hold? How many liters?

Yes, the answer is 128,000 cm^3 or ml.

A milliliter and a cubic centimeter are the same thing. Both are volume units, and apply to any fluid...not just water.

Divide by 1000 for the number of liters.

drwls told you the answer.

easier way, (the beauty of the metric system)

original is 80 cm by 40 cm by 40 cm

= 8 dm by 4 dm by 4 dm

volume = 128 dm^3

= **128 L** , since 1 L = 1 dm^3 of liquid

Oh I get how to get the Liters now cause 128x1000=128000 from problem 6

How about mL?
