The volume is multiplied by 8. For example if you have a 1x1x1 cube the volume is 1. If you have a 2x2x2 cube the volume is 8. If you have a 4x4x4 the volume is 64.
Example: Set up proportions.
3/4 cups → 1 batch
x cups → 2 batches
x = 2(3/4) = 6/4 = 1 1/2 cups
3/4 cups → 1 batch
y cups → 9 batches
y = 9(3/4) = 6 3/4 cups

Answer:
The value of x for the given expression is (95/27)
Step-by-step explanation:
Here, the given expression is:

Now here solving for the value of x , we get

Now, taking the variable terms on 1 side, we get

or, 
Hence, the value of x = (95/27)
