<think>Okay, let's see. Albert wants to know how much pizza he can eat in a day, and he bought 2 large pizzas and 2 small ones. I need to figure out how many slices that is in total if he eats all of them. Hmm, first, let's make sure I understand the problem correctly. So each large pizza has 16 slices, and each small pizza has 8 slices. Albert buys two of each. So the total number of slices would be the sum of the slices from the large pizzas and the small ones. 

Wait, maybe I should break it down step by step. Alright, the first step is to calculate how many slices are in the large pizzas. He has 2 large pizzas, each with 16 slices. So that's 16 slices per large pizza multiplied by 2. Let me write this out: 16 (slices) * 2 (pizzas) = 32 slices from the large pizzas.

Next, the small pizzas. He also bought 2 small ones, and each small pizza has 8 slices. So that would be 8 slices multiplied by 2 pizzas. Let me check: 8 * 2 = 16 slices from the small pizzas.

Now, adding those two results together should give the total number of slices Albert eats. So 32 slices from large pizzas plus 16 slices from small pizzas equals... hmm, 32 + 16 is 48. So 48 slices in total.

But wait, let me verify that again to be sure. Maybe I mixed up the numbers. Let's go through each part again. 

Large pizzas: 2 pizzas × 16 slices each. 2 × 16 is indeed 32. Then small pizzas: 2 pizzas × 8 slices each. 2 × 8 is 16. Adding 32 and 16 gives 48. Hmm, that seems right. Let me visualize: if he eats two whole large pizzas, each with 16 slices, he's eating 32. Then two small ones, each 8, giving another 16. Total 48. Yeah, that makes sense. Wait, just checking if there's any trick to the problem. The question says "how many pieces does he eat that day if he eats it all." It doesn't mention anything about sharing with others or not eating all, so we can assume he eats everything by himself. Therefore, the total is 48 slices. 

I don't see any errors in the calculation. Multiplication for each pizza size and then adding the results. Simple enough. So I think the answer is 48.

Albert eats a total of **48 slices** of pizza that day. Here’s the breakdown:

1. **Large Pizzas**:  
   \(2 \text{ pizzas} \times 16 \text{ slices/pizza} = 32 \text{ slices}\)  
2. **Small Pizzas**:  
   \(2 \text{ pizzas} \times 8 \text{ slices/pizza} = 16 \text{ slices}\)  
3. **Total Slices**:  
   \(32 \text{ slices} + 16 \text{ slices} = 48 \text{ slices}\)  

**Final Answer**: \boxed{48}
