Sarah is selling lemonade. she has sold a total 0f 14 cups . 4 cups were sold to adults and she sold 2 batches of lemonade to other children. how many cups were in each batch?

If Sarah has a total of 14 cups to start and uses all of them, we know the following...

Start: 14 cups

14 cups - 4 cups = 10 cups after she had sold cups to adults

10 cups are left

Sarah sells 10 cups to children (2 batches)

10 cups / 2 batches = 5 cups in each batch

The density of the cube is 40
