Q: Josh wants to build a square sandbox that is 3 ft long, 3 ft wide for his son. He can buy sand in 3 sq ft bags for $4.00 a bag. How much will it cost him to fill up the sandbox?
A: The sandbox is 3' long, 3' wide so the sq footage of the sandbox is 3 * 3 = 9 sq ft.

The sand costs $4.00 a bag and he needs 3 bags so it will cost him 4 * 3 = $12.00 in sand. The answer is 12.

[Question]Ivory and Brayan are doing school projects with a tight deadline and have to stay up late to complete everything. They prepare coffee to help them stay focused. If Brayan drinks twice as much coffee as Ivory, and Brayan drinks 4 cups of coffee in an hour, calculate the total number of cups of coffee they drink together in 5 hours.
