Question

Barry has a rectangular prism shaped garden with the following dimensions, 4 feet by 2.5 feet by 2 feet. If soil costs $5.75 per cubic foot, how much will is cost for Barry to fill his garden with soil?

(hint: find volume in cubic feet first) (And explanation too please!)

Answer 1

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.
