Introduction

In this problem, we are tasked with determining the amount of paint needed to cover all six sides of a jewelry box. To solve this, we need to calculate the surface area of the box, which includes the areas of the top and bottom bases, as well as the four sides. This problem requires an understanding of basic geometry and surface area calculations.

Calculating the Surface Area of the Jewelry Box

To calculate the surface area of the jewelry box, we need to find the area of one base and then multiply it by 2 (for the top and bottom bases). We also need to find the area of one side and then multiply it by 4 (for the four sides).

Step 1: Calculating the Area of One Base

Let's assume the base of the jewelry box is a square with side length s. The area of one base is given by the formula:

Area of one base = s^2

Step 2: Calculating the Area of One Side

The area of one side of the jewelry box is given by the formula:

Area of one side = s * h

where h is the height of the jewelry box.

Step 3: Calculating the Total Surface Area

The total surface area of the jewelry box is the sum of the areas of the top and bottom bases, as well as the four sides. This can be calculated using the following formula:

Total surface area = 2 * (s^2) + 4 * (s * h)

Simplifying the Formula

We can simplify the formula by combining like terms:

Total surface area = 2s^2 + 4sh

Example: Calculating the Paint Needed for a Jewelry Box

Let's assume the side length of the base is 10 cm and the height of the jewelry box is 5 cm. We can plug these values into the formula to calculate the total surface area:

Total surface area = 2(10)^2 + 4(10)(5) Total surface area = 2(100) + 4(50) Total surface area = 200 + 200 Total surface area = 400 cm^2

Therefore, Tamara needs 400 cm^2 of paint to cover all six sides of the jewelry box.

Conclusion

In this problem, we calculated the surface area of a jewelry box using basic geometry and algebra. We found that the total surface area is the sum of the areas of the top and bottom bases, as well as the four sides. By plugging in the values of the side length and height, we were able to calculate the total surface area and determine the amount of paint needed to cover all six sides of the jewelry box.

Area of one side = s * h

where s is the side length of the base and h is the height of the jewelry box.

Q: What if the jewelry box is not a perfect square or rectangle?

A: If the jewelry box is not a perfect square or rectangle, you will need to calculate the surface area of each individual side and then add them together. This can be a more complex calculation, but the basic principle remains the same.

Q: How do I determine the amount of paint needed for a jewelry box?

A: To determine the amount of paint needed for a jewelry box, you will need to calculate the total surface area of the box and then multiply it by the number of coats of paint you want to apply. You will also need to consider the type of paint you are using and the surface area of the box that will be covered by each coat.

Q: What if I'm not sure what the dimensions of the jewelry box are?

A: If you're not sure what the dimensions of the jewelry box are, you can try measuring it or using a ruler to estimate the dimensions. You can also use a calculator to help you calculate the surface area.

Q: Can I use a calculator to help me calculate the surface area of a jewelry box?

A: Yes, you can use a calculator to help you calculate the surface area of a jewelry box. In fact, using a calculator can make the calculation much easier and faster.

Q: What if I make a mistake in my calculation?

A: If you make a mistake in your calculation, don't worry! You can always recheck your work and try again. It's also a good idea to double-check your calculations with a calculator or by using a different method.
