Final answer:
The total volume of the two crates is 108 liters.
Step-by-step explanation:
To find the total volume of the two crates, we first need to calculate the volume of each crate separately and then add them together.
In the first crate, there are 4 layers of 12 cartons, each carton containing 1.35 liters of soup. So, the total volume in the first crate is 4 x 12 x 1.35 = 64.8 liters.
In the second crate, there are 32 cartons, each containing 1.35 liters of soup. So, the total volume in the second crate is 32 x 1.35 = 43.2 liters.
Adding both volumes, the total volume of the two crates is 64.8 + 43.2 = 108 liters.
