Final answer:
To find the cubic feet of soil Miyako needs for her garden bed, calculate the volume by multiplying the length, width, and height of the bed. The dimensions were not provided, so an example was given instead.
Step-by-step explanation:
To calculate the amount of soil Miyako needs to fill her raised garden bed, which is a right rectangular prism, you need to find the volume by multiplying the length, width, and height of the garden bed. The volume is given by the formula V = length × width × height. Unfortunately, the specific dimensions of Miyako's garden bed were not provided, but once you have them, simply apply this formula to find the volume in cubic feet of soil required.
For example, if the garden bed measures 10 feet in length, 5 feet in width, and 2 feet in height, the volume would be calculated as V = 10 ft × 5 ft × 2 ft = 100 cubic feet. Therefore, Miyako would need 100 cubic feet of soil to fill the raised garden bed of these dimensions.
