Answer 23

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?

[1 foot = 12 inches]

Answer 24

First we must do V = lwh
But to do that we must convert 5 feet to inches
5 ft = 60

Now plugging it in you do

60 * 6 * 9

Answer 25

Now how many inches is it?

Answer 26

3,240

Answer 27

And now we need to convert that back to feet again because they are using 0.625 cubic feet

So we you just do

3,240 divided by 12

Answer 28

270

Answer 29

and now divide by

270/ 0.625

Answer 30

432

Answer 31

doesnt even make sence

Answer 32

What doesn't make sense?

Answer 33

270 divided by .625 comes out to 432

Answer 34

because it's a decimal, and when you multiply a decimal by a whole number it goes smaller, dividing it makes it bigger. It's because it's not over 0

Answer 35

But yea, he will need 432 bags of soil
