256 are needed because 32x1=32 that means the ratio would be 32:256 because 8 x 32 = 256 The final ratio would stay the same as 1:8 though because it would be simplified. Hope this helped.
To maintain the 1:8 ratio of powdered drink mix to water, for 32 cups of powder, you need 256 cups of water. This is calculated by multiplying the cups of powder by 8. Thus, the total amount of water needed is 256 cups.
