Surface Area Of A Cuboid Whose Length Of Breath And Height Are Restrictively 3 CM To Cm And 1.5 Cm Is
Introduction
In geometry, a cuboid is a three-dimensional solid object with six rectangular faces. The surface area of a cuboid is the total area of its six faces. In this article, we will discuss the formula and calculations for finding the surface area of a cuboid, with a specific focus on a cuboid with a length of breath and height of 3 cm to cm and 1.5 cm.
What is Surface Area?
The surface area of a cuboid is the total area of its six faces. It is calculated by finding the area of each face and adding them together. The surface area of a cuboid can be calculated using the formula:
Surface Area = 2(lb + bh + hl)
where l is the length, b is the breadth, and h is the height of the cuboid.
Calculating Surface Area of a Cuboid
To calculate the surface area of a cuboid, we need to know its length, breadth, and height. Let's consider a cuboid with a length of 3 cm, breadth of 4 cm, and height of 1.5 cm.
Step 1: Identify the Dimensions
- Length (l) = 3 cm
- Breadth (b) = 4 cm
- Height (h) = 1.5 cm
Step 2: Calculate the Surface Area
Using the formula, we can calculate the surface area of the cuboid as follows:
Surface Area = 2(lb + bh + hl) Surface Area = 2(3 x 4 + 4 x 1.5 + 3 x 1.5) Surface Area = 2(12 + 6 + 4.5) Surface Area = 2(22.5) Surface Area = 45
Therefore, the surface area of the cuboid is 45 square centimeters.
Real-World Applications
The surface area of a cuboid has many real-world applications. For example:
- Packaging: When designing a package for a product, the surface area of the package is an important consideration. The surface area of the package will determine the amount of material needed to cover it.
- Construction: When building a structure, the surface area of the walls and roof is an important consideration. The surface area of the walls and roof will determine the amount of material needed to cover them.
- Design: When designing a product, the surface area of the product is an important consideration. The surface area of the product will determine its aesthetic appeal and functionality.
Conclusion
In conclusion, the surface area of a cuboid is an important concept in geometry. The formula for calculating the surface area of a cuboid is Surface Area = 2(lb + bh + hl). By understanding this formula and how to calculate the surface area of a cuboid, we can apply it to real-world problems and design more efficient and effective solutions.

Surface Area of a Cuboid: Q&A ================================
Introduction
In our previous article, we discussed the formula and calculations for finding the surface area of a cuboid. In this article, we will answer some frequently asked questions about the surface area of a cuboid.
Q&A
Q: What is the surface area of a cuboid?
A: The surface area of a cuboid is the total area of its six faces.
Q: How do I calculate the surface area of a cuboid?
A: To calculate the surface area of a cuboid, you need to know its length, breadth, and height. Use the formula Surface Area = 2(lb + bh + hl).
Q: What are the dimensions of a cuboid?
A: A cuboid has three dimensions: length (l), breadth (b), and height (h).
Q: How do I find the surface area of a cuboid with a length of 5 cm, breadth of 3 cm, and height of 2 cm?
A: To find the surface area of a cuboid with a length of 5 cm, breadth of 3 cm, and height of 2 cm, use the formula Surface Area = 2(lb + bh + hl).
Surface Area = 2(5 x 3 + 3 x 2 + 5 x 2) Surface Area = 2(15 + 6 + 10) Surface Area = 2(31) Surface Area = 62
Therefore, the surface area of the cuboid is 62 square centimeters.
Q: What are the real-world applications of the surface area of a cuboid?
A: The surface area of a cuboid has many real-world applications, including:
- Packaging: When designing a package for a product, the surface area of the package is an important consideration. The surface area of the package will determine the amount of material needed to cover it.
- Construction: When building a structure, the surface area of the walls and roof is an important consideration. The surface area of the walls and roof will determine the amount of material needed to cover them.
- Design: When designing a product, the surface area of the product is an important consideration. The surface area of the product will determine its aesthetic appeal and functionality.
Q: Can I use the surface area formula for other shapes?
A: No, the surface area formula for a cuboid is specific to cuboids. However, you can use similar formulas for other shapes, such as:
- Surface Area of a Cube = 6s^2 (where s is the side length)
- Surface Area of a Rectangular Prism = 2lw + 2lh + 2wh (where l is the length, w is the width, and h is the height)
Q: How do I find the surface area of a cuboid with a length of 10 cm, breadth of 5 cm, and height of 3 cm?
A: To find the surface area of a cuboid with a length of 10 cm, breadth of 5 cm, and height of 3 cm, use the formula Surface Area = 2(lb + bh + hl).
Surface Area = 2(10 x 5 + 5 x 3 + 10 x 3) Surface Area = 2(50 + 15 + 30) Surface Area = 2(95) Surface Area = 190
Therefore, the surface area of the cuboid is 190 square centimeters.
Conclusion
In conclusion, the surface area of a cuboid is an important concept in geometry. By understanding the formula and calculations for finding the surface area of a cuboid, you can apply it to real-world problems and design more efficient and effective solutions.
