Which unit of measure would be best to use to measure the capacity of a fish tank?

Ml/cm^3 (same measurement) would be the best unit. 

Reason
cm can be measured with a simple ruler. Once you have area of the tank (length x width), it can be multiplied by the height to give you the unit it cm^3. 

Water is measured in ml, which would make it easy to get the right amount because you now know the capacity!

Hopefully this helps :)

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
