Calculating Milk Truckloads A Supermarket Problem
Introduction
Hey guys! Let's dive into a fun problem today that involves a bit of math and real-world application. We're going to figure out how many trucks it takes to deliver a supermarket's monthly milk supply. This is a common type of question you might encounter, especially in exams like the ENEM (Exame Nacional do Ensino Médio) in Brazil, which tests your ability to apply mathematical concepts to everyday scenarios. So, grab your thinking caps, and let's get started!
Problem Statement
The problem we're tackling today is: A supermarket sold 33,000 liters of milk in April. If each truck carrying milk has a capacity of 11 cubic meters, how many truckloads were unloaded at the supermarket? This question requires us to convert units and perform a simple division to find the answer. Let's break it down step by step.
Understanding the Problem
Before we jump into the calculations, let's make sure we fully understand the problem. The key here is to recognize that we're dealing with two different units of volume: liters and cubic meters. We know the total volume of milk sold in liters and the capacity of each truck in cubic meters. To find the number of trucks, we need to convert these units so that they are the same. This conversion is a crucial step in solving the problem accurately. So, let's dive deeper into unit conversion before proceeding further. We need to convert liters to cubic meters or vice versa to make the units uniform for our calculation.
Importance of Unit Conversion
In many real-world problems, including those in mathematics and physics, unit conversion is super important. It ensures that we're comparing apples to apples, so to speak. Imagine trying to add 5 meters to 10 centimeters without converting them first – the result wouldn't make much sense! Similarly, in our milk truck problem, we can't directly divide liters by cubic meters. Unit conversion allows us to express quantities in a consistent manner, leading to accurate results. This skill is not only essential for solving mathematical problems but also for practical applications in fields like engineering, chemistry, and even cooking!
Common Unit Conversions
There are several common unit conversions that you should be familiar with. For volume, some of the most frequently used conversions include liters to cubic meters, milliliters to liters, and gallons to liters. In our case, we need to know the relationship between liters and cubic meters. Remember that 1 cubic meter is equal to 1000 liters. This conversion factor is crucial for solving our problem. Knowing other conversions, such as those for length (meters to centimeters, kilometers to miles) and weight (kilograms to pounds), can also come in handy in various situations. So, make sure you have these conversions at your fingertips!
Step-by-Step Solution
Now that we have a solid understanding of the problem and the importance of unit conversion, let's solve it step by step. This will help you see exactly how to approach similar problems in the future. Follow along, and you'll master this type of calculation in no time!
Step 1: Convert Cubic Meters to Liters
The first thing we need to do is convert the truck's capacity from cubic meters to liters. We know that 1 cubic meter (m³) is equal to 1000 liters (L). The truck has a capacity of 11 m³, so we need to multiply this by the conversion factor:
11 m³ * 1000 L/m³ = 11,000 L
So, each truck can carry 11,000 liters of milk. Now we have both quantities in the same unit, which is liters. This makes it much easier to compare the truck's capacity with the total milk sold by the supermarket. Next, we'll use this information to calculate the number of truckloads required.
Step 2: Calculate the Number of Truckloads
Now that we know the supermarket sold 33,000 liters of milk and each truck carries 11,000 liters, we can calculate the number of truckloads by dividing the total amount of milk by the capacity of each truck:
Number of truckloads = Total liters of milk / Capacity per truck
Number of truckloads = 33,000 L / 11,000 L/truck
Number of truckloads = 3
Therefore, the supermarket needed 3 truckloads to deliver the 33,000 liters of milk sold in April. This simple division gives us the answer we're looking for. Isn't it cool how math can help us solve real-world problems like this?
Final Answer
So, after working through the problem step by step, we've arrived at the solution: 3 truckloads of milk were unloaded at the supermarket in April. This means that three trucks, each carrying 11,000 liters of milk, were needed to meet the supermarket's sales for the month. This is a clear and concise answer that directly addresses the question asked. Remember, in exams like ENEM, it's essential to not only get the correct answer but also to present it clearly and logically. And now, let's take a look at some strategies for tackling similar problems in the future.
