Solve The Following Multiplication Problem: 15 Ft × 18 Ft 15 \, \text{ft} \times 18 \, \text{ft} 15 Ft × 18 Ft
Introduction
In mathematics, multiplication is a fundamental operation that involves the repeated addition of a number. When dealing with lengths, such as feet or meters, multiplication can be used to find the area of a rectangle or the volume of a rectangular prism. In this article, we will focus on solving a multiplication problem involving lengths, specifically the product of 15 feet and 18 feet.
Understanding the Problem
The problem we are trying to solve is: . This means we need to multiply 15 feet by 18 feet to find the result. To approach this problem, we can use the concept of repeated addition, where we add 15 feet together 18 times.
Breaking Down the Problem
To make the problem more manageable, let's break it down into smaller parts. We can start by multiplying 15 feet by 10 feet, and then multiply the result by 8 feet (since 18 feet is equal to 10 feet + 8 feet).
Step 1: Multiply 15 feet by 10 feet
To multiply 15 feet by 10 feet, we can use the concept of repeated addition. We can add 15 feet together 10 times:
15 ft + 15 ft + 15 ft + 15 ft + 15 ft + 15 ft + 15 ft + 15 ft + 15 ft + 15 ft = 150 ft
So, the result of multiplying 15 feet by 10 feet is 150 feet.
Step 2: Multiply 150 feet by 8 feet
Now that we have the result of multiplying 15 feet by 10 feet, we can multiply it by 8 feet:
150 ft × 8 ft = 1200 ft²
The Final Result
Therefore, the final result of multiplying 15 feet by 18 feet is 1200 square feet.
Conclusion
In this article, we have solved a multiplication problem involving lengths, specifically the product of 15 feet and 18 feet. We used the concept of repeated addition to break down the problem into smaller parts and then multiplied the results together to find the final answer. This approach can be applied to other multiplication problems involving lengths, such as finding the area of a rectangle or the volume of a rectangular prism.
