Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Tony has a bucket that holds 2 pounds of sand. He has a sandbox out back that is two feet deep, four feet wide, and 5 feet long. A cubic foot of sand weighs 3 pounds. Because it's hot outside, he wants to make sure he stays hydrated, so every 4 trips he takes he drinks 3 ounces of bottled water. A 15 ounce bottle of water costs $2. He has $10 with him. How much change will he have after he buys all the water he needs?


### Response:
 Le bac à sable a une capacité de 40 pieds cubes car 2 ft x 4 ft x 5 ft = <<2*4*5=40>>40 pieds cubes
Il a besoin de 120 livres de sable car 40 pieds cubes x 3 livres/pied cube = <<40*3=120>>120 livres
Il fera 60 voyages car 120 / 2 = <<120/2=60>>60
Il devra boire de l'eau 15 fois car 60 / 4 = <<60/4=15>>15
Il boira 45 onces d'eau car 15 x 3 = <<15*3=45>>45
Il aura besoin de 3 bouteilles d'eau car 45 / 15 = <<45/15=3>>3
Il dépensera 6 $ en eau car 3 x 2 = <<3*2=6>>6
Il aura 4 $ de monnaie car 10 - 6 = <<10-6=4>>4
