Question

I'm between 3 and 10 D:

Zen wants to fill a window box with soil. The length of the window box is 5 feet, width is 6 inches, and height is 9 inches. Each bag of soil contains 0.625 cubic foot of soil. How many bags of soil will Zen need to fill the window box completely?

Answer 1

Well, the imperial system sucks.
If you know the volume of the box and the volume of the soil, just change the units so that they are the same, either cubic feet or inches I suppose, then it becomes a simple problem.

Answer 2

You need to make sure that you have the same units for everything. So we have 5 feet, 6 inches, and 9 inches that we need to multiply together. 6 inches=.5 feet and 9 inches=.75 feet.

Multiplying (5)(.5)(.75)=1.875.

We know that each bag of soil contains .625 cubic feet of soil. So we divide 1.875/.625 to determine the number of bags of soil needed to fill the box completely and get an answer of 3 bags.

Answer 3

What if i wanted to convert everything to feet?

Answer 4

See my previous post-everything is converted to feet.

Answer 5

Oh, I meant inches*

Answer 6

Then you're just trying to make this harder on yourself. The bags contain cubic feet of soil, so you really only need feet. But if you were to do inches, anything that began in feet needs to be multiplied by 12 (because there are 12 inches in a foot).

Answer 7

Oh ok, ty!

Answer 8

You're welcome!
