Answer: To find the cost of filling Barry's rectangular prism-shaped garden with soil, we need to follow these steps:
Calculate the volume of the rectangular prism using the given dimensions:
Volume = Length × Width × Height
Given:
- Length = 4 feet
- Width = 2.5 feet
- Height = 2 feet
Volume = 4 ft × 2.5 ft × 2 ft
= 20 ft³
Now that we have the volume in cubic feet, we can find the cost by multiplying the volume by the cost per cubic foot:
Cost = Volume × Cost per cubic foot
Given:
- Cost per cubic foot = $5.75
- Cost = 20 ft³ × $5.75/ft³
- = $115
Therefore, it will cost Barry $115 to fill his garden with soil.
