Introduction

When it comes to designing a classroom bulletin board, one of the most crucial factors to consider is the total area of the surface. This is because the area will determine how much space is available for displaying information, posters, and other visual aids. In this article, we will explore how to calculate the total area of a classroom bulletin board using basic mathematical concepts.

Understanding the Problem

The problem states that the classroom bulletin board is $$\frac{10^2}{3}$$ feet long and $$\frac{41}{5}$$ feet wide. To find the total area of the surface, we need to multiply the length and width of the board.

Calculating the Length and Width

To start, let's calculate the length and width of the bulletin board.

Length: $$\frac{10^2}{3} = \frac{100}{3}$$ feet
Width: $$\frac{41}{5}$$ feet

Multiplying the Length and Width

Now that we have the length and width, we can multiply them together to find the total area of the surface.

\text{Area} = \text{Length} \times \text{Width}

\text{Area} = \frac{100}{3} \times \frac{41}{5}

Simplifying the Expression

To simplify the expression, we can multiply the numerators and denominators separately.

\text{Area} = \frac{100 \times 41}{3 \times 5}

\text{Area} = \frac{4100}{15}

Reducing the Fraction

To reduce the fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD).

\text{GCD}(4100, 15) = 5

\text{Area} = \frac{4100 \div 5}{15 \div 5}

\text{Area} = \frac{820}{3}

Converting the Fraction to a Decimal

To convert the fraction to a decimal, we can divide the numerator by the denominator.

\text{Area} = \frac{820}{3} = 273.33

Conclusion

In conclusion, the total area of the surface of the classroom bulletin board is $$\frac{820}{3}$$ square feet, which is equivalent to 273.33 square feet.

Discussion

The problem requires us to use basic mathematical concepts, such as multiplication and simplification of fractions, to find the total area of the surface of the bulletin board. This type of problem is essential in real-world applications, such as designing and building structures, where the total area of a surface is crucial in determining the amount of materials needed.

Final Answer

The final answer is $$\frac{820}{3}$$ square feet.
