If the box is 4 inches tall, then its height is 4in.  Since the width is twice the height, the width must be 8 inches.  Since the length is three times the width, the length must be 24 inches.  Since a rectangular box is just a rectangular solid, the formula for the volume of a rectangular solid will give us the volume of the Trayvon's box.

, where  is length,  is width, and  is height.  Therefore,

Since the unit of each of our dimensions was inches, our volume will be in cubic inches.  Thus our answer is 

Divide each dimension in inches by 12 to convert from inches to feet:

 feet

 feet

 feet

Multiply the three to get the volume:

 cubic feet

In order to figure out how many cubic centimeters can fit into the box, we need to figure out the volume of the box in terms of cubic centimeters. However, the measurements of the box are given in meters. Therefore, we need to convert these measurements to centimeters and then determine the volume of the box.

There are 100 centimeters in one meter. This means that in order to convert from meters to centimeters, we must multiply by 100.

The length of the box is 2 meters, which is equal to 2 x 100, or 200, centimeters.

The width of the box is 0.5(100) = 50 centimeters.

The height of the box is 3.2(100) = 320 centimeters.

Now that all of our measurements are in centimeters, we can calculate the volume of the box in cubic centimeters. Remember that the volume of a rectangular box (or prism) is equal to the product of the length, width, and height.

V = length x width x height

V = (200 cm)(50 cm)(320 cm) = 3,200,000 cm³

To rewrite this in scientific notation, we must move the decimal six places to the left.

V = 3.2 x 10⁶ cm³

The answer is 3.2 x 10⁶.

To find the volume of a cube, we multiply length by width by height, which can be represented with the forumla .  Since a cube has equal sides, we can use for all three values.

The volume of a a cube (or rectangular prism) can be solved using the following equation:

Let  be the length of an edge of the cube. The volume of a cube can be determined by the equation:

The volume of a given prism , where  is the base area and  is the height. For a rectangular prism, the base area , or length times width. Therefore:

Substituting in our known values:

The volume  of a rectangular prism is the product of its base area  and its height : . Since we can determine the base area of the rectangular prism from its length and width, we can rewrite the equation and solve:

The volume  of a rectangular prism is the product of its base area  and its height : . Since we can determine the base area of the rectangular prism from its length and width, we can rewrite the equation and solve:

Write the formula to find the volume of a rectangular solid.

Substitute the dimensions.
