Kenny buys 4 1liter bottles of water how many millileters of water does Kenny buy

Kenny bought 4 1liter bottles of water

1liter is equal to 1,000 milliliters (milli means 1,000)

What that means is that in each bottle of water that he purchased, he has 1,000 milliliters

He has 4 bottles, so we simply take

4 (bottles) x 1,000 (amount of water in each bottle)

4 x 1,000 = 4,000 milliliters
