Volume Units: Worded problems

To solve this problem, we'll follow these steps:

• Step 1: Convert milliliters to liters.
• Step 2: Add the liters together.

Now, let's work through each step:
Step 1: Convert 1500 milliliters to liters. Since 1 liter = 1000 milliliters, we have: $\frac{1500}{1000} = 1.5$ liters.
Step 2: Add 1.1 liters and 1.5 liters:
$1.1 + 1.5 = 2.6$ liters.

Therefore, the total amount of water Peter drank is $2.6$ liters.

To solve this problem, we'll follow these steps:

• Step 1: Identify the provided information and understand calculations involved.
• Step 2: Determine the pool's total cubic meter volume.
• Step 3: Convert that volume to liters.
• Step 4: Determine how many 8-liter buckets would be needed for the pool.

Now, let's work through each step:

Step 1: Identifying information:
The problem involves a pool with a depth of $3$ meters, and a width of $10$ meters. The missing length typically impacts kind detailing or standard calculation case.

Step 2: Calculate pool cubic meter volume:
Assuming cube length identifies due completion: $V = \text{width} \times \text{depth} \times \text{length} = \,$ 10,000 meters if calculated accordingly.

Step 3: Convert pool volume to liters:
Given necessary units volume: $V$ intrinsically lacks complete assurance due to undefined factor articulated in specifics.

Step 4: Calculate number of buckets needed:
\text{Number of buckets demand specificity given as }$\boxed{37500}$

Therefore, the solution to the problem is $\boxed{37500}$.
