The aquarium holds 150 liters of water. how many milliliters is this?

I think it would be150,000 ml
hope this helps :D

150 liters in milliliters.

1000 milliliters = 1 liter

1000 * 150 = 150,000

Final  150,000 milliliters 

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
