Convert 57.4in^3 to yd^3. show work

First thing to know
36in = 1 yd

If that ^ mean x 3, then

57.4in x3 = 172.2in

In to yd =

172.2/36= 4.783yd

Now we yards.

Again if the ^ 3 mean x 3, the

4.783yd x 3 = 14.35yd

Ans = 14.35 yards

36in = 1

If the ^3 means to the power of 3, then

57.4 x 57.4 x57.4 = 189119.224in.

So, if 36in = 1yd, then we have to divide this answer by 36 to see how many yds in there.

189119.224 /36 = 5253.311777778yd
Rounded up= 5253.312yd.

Again if ^ 3 means to the power of 3, then we have to do the same

5253.312x 5253.312 x 5253.312 = 144977158803 yds

And= 144977158803 yards
