Jack wants to fill a rectangular box with sand. The length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inches. Each bag of sand contains 0.15 cubic foot of sand. How many bags of sand will Jack need to fill the box completely? [1 foot = 12 inches] Numerical Answers Expected! Answer for Blank 1:

Someone help me please.
The volume of the rectangular box will come from multiplying the length by width by height. Because the bags of sand are in cubic feet, change the dimensions so that they are in terms of feet.
Yes, so how would I do that. How would I set this up to solve it?
First, get the volume in terms of cubic feet. The length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inches. V = 3 * (6/12) * (2.4/12) cubic feet. Simplify that. Then, there's a little more to do.
Okay give me a sec to simplify.
I got 0.3
That is what I got. So, the volume is .3 cubic feet.
We are filling the box with sand. Each bag of sand holds .15 cubic feet. Each bag of sand contains 0.15 cubic foot of sand.
To get the number of needed bags, divide .3 by .15. .3/.15 = ?
What did you get? I got 2 also, so we need 2 bags of sand.
So it is 2 right?
