Introduction

When it comes to packing materials, we often think of boxes as being filled with items, but what about the empty box itself? In this scenario, we have an empty rectangular prism box with a base area of $\frac{9}{10}$ square foot and a height of $\frac{1}{3}$ foot. The question is, how much packing material is required to fill the box?

Understanding the Problem

To determine the amount of packing material needed, we need to calculate the volume of the empty box. The volume of a rectangular prism is given by the formula:

Volume = Base Area x Height

In this case, the base area is $\frac{9}{10}$ square foot, and the height is $\frac{1}{3}$ foot. Plugging these values into the formula, we get:

Volume = $\frac{9}{10}$ x $\frac{1}{3}$

To find the product of these fractions, we multiply the numerators (9 and 1) and the denominators (10 and 3):

Volume = $\frac{9}{10}$ x $\frac{1}{3}$ = $\frac{9}{30}$

Simplifying the fraction, we get:

Volume = $\frac{3}{10}$

So, the volume of the empty box is $\frac{3}{10}$ cubic foot.

Calculating the Packing Material Required

Now that we have the volume of the box, we can calculate the amount of packing material required to fill it. Since the packing material will fill the entire box, we need to find the volume of the packing material that is equal to the volume of the box.

Packing Material Volume = Box Volume

In this case, the packing material volume is also $\frac{3}{10}$ cubic foot.

Converting the Volume to a More Meaningful Unit

To make the volume more meaningful, we can convert it to a more common unit, such as cubic inches. There are 12 inches in a foot, so we can convert the volume as follows:

1 cubic foot = 12 x 12 x 12 = 1728 cubic inches

Now, we can convert the volume of the box from cubic feet to cubic inches:

Volume = $\frac{3}{10}$ cubic foot x 1728 cubic inches/cubic foot

To perform this conversion, we multiply the fraction by the conversion factor:

Volume = $\frac{3}{10}$ x 1728 = 518.4 cubic inches

So, the volume of the empty box is approximately 518.4 cubic inches.

Conclusion

In conclusion, to determine the amount of packing material required to fill an empty rectangular prism box, we need to calculate the volume of the box. In this scenario, the volume of the box is $\frac{3}{10}$ cubic foot, which is equivalent to approximately 518.4 cubic inches. This means that the packing material required to fill the box is also $\frac{3}{10}$ cubic foot or approximately 518.4 cubic inches.

Final Answer

Introduction

In our previous article, we discussed how to calculate the amount of packing material required to fill an empty rectangular prism box. In this article, we will answer some frequently asked questions related to this topic.

Q: What is the formula for calculating the volume of a rectangular prism?

A: The formula for calculating the volume of a rectangular prism is:

Volume = Base Area x Height

This formula is used to find the volume of the box, which is then used to determine the amount of packing material required.

Q: How do I calculate the base area of a rectangular prism?

A: The base area of a rectangular prism is calculated by multiplying the length and width of the base. For example, if the length of the base is 6 inches and the width is 4 inches, the base area would be:

Base Area = Length x Width = 6 x 4 = 24 square inches

Q: What if the base area is given as a fraction? How do I convert it to a decimal?

A: If the base area is given as a fraction, you can convert it to a decimal by dividing the numerator by the denominator. For example, if the base area is $\frac{9}{10}$ square foot, you can convert it to a decimal as follows:

Base Area = $\frac{9}{10}$ = 0.9 square foot

Q: How do I convert the volume of the box from cubic feet to cubic inches?

A: To convert the volume of the box from cubic feet to cubic inches, you can multiply the volume in cubic feet by the conversion factor:

1 cubic foot = 12 x 12 x 12 = 1728 cubic inches

For example, if the volume of the box is $\frac{3}{10}$ cubic foot, you can convert it to cubic inches as follows:

Volume = $\frac{3}{10}$ cubic foot x 1728 cubic inches/cubic foot = 518.4 cubic inches

Q: What if the height of the box is given as a fraction? How do I convert it to a decimal?

A: If the height of the box is given as a fraction, you can convert it to a decimal by dividing the numerator by the denominator. For example, if the height is $\frac{1}{3}$ foot, you can convert it to a decimal as follows:

Height = $\frac{1}{3}$ = 0.33 foot

Q: Can I use this formula to calculate the packing material required for a box with a non-rectangular base?

A: No, this formula is only applicable to rectangular prisms with a rectangular base. If the base is non-rectangular, you will need to use a different formula to calculate the volume of the box.

Q: What if I have a box with a non-uniform height? How do I calculate the packing material required?

A: If the box has a non-uniform height, you will need to calculate the volume of the box by integrating the area of the base with respect to the height. This is a more complex calculation and may require the use of calculus.

Conclusion

In conclusion, calculating the amount of packing material required to fill an empty rectangular prism box involves using the formula for the volume of a rectangular prism. By following the steps outlined in this article, you can easily calculate the packing material required for a box with a rectangular base and uniform height.
