Answer 1

48 bags.

First, calculate the total volume of the vegetable garden:

Volume = Length x Width x Depth
Volume = 8 ft x 22 ft x 0.25 ft (convert 3 inches to feet)
Volume = 44 cubic feet

Then, calculate how many bags of mulch Lexi needs:

Number of bags = Total volume / Volume per bag
Number of bags = 44 cubic feet / 2 cubic feet
Number of bags = 22 bags

Therefore, Lexi should purchase 48 bags of mulch.
