# Thread: if any one can help me out

1. ## if any one can help me out

I'm doing this lesson for pre algebra and I've gotten this question wrong 3 times already. the question is. Use six unit multipliers to convert 24,000,000 cubic inches to cubic yards? If anyone can help get me aheading in the right direction I'd gladly appreciate it.

Hi kuttluse,

I don't know why you need 6 unit mutipliers. The simplest way is:

$24000000 \; in^3 \times \frac{(1 \; yd)^3}{(36 \; in)^3}\approx 514.4 \; yd^3$

You could muddy the waters by

$24000000 \; in^3 \times \frac{1 \; ft}{12 \; in}\times \frac{1 \;ft}{12 \; in}\times \frac{1\; ft}{12 \; in}\times \frac{1 \; yd}{3 \;ft} \times \frac{1 \; yd}{3 \;ft} \times \frac{1 \; yd}{3 \;ft} \approx 514.4 \; yd^3$

3. thanks I did that one time b4 but I didn't get that as my answer I actionly tried that way first thanks
