Choices:

100 x 60 x 1.5

100 x 60 x 2

90 x 60 x 2

90 x 60 x 1.5

**Steve**, Wednesday, May 21, 2014 at 3:49pmRounding each value to the nearest single-significant-digit approximation, that would be

90x60x2

I'd choose that instead of 100*60 because in that case both values are rounded up, making the estimate too high.

**Damon**, Wednesday, May 21, 2014 at 3:51pmLOL, well there is one sure way to find out

93 * 58 * 2.47 = 13,323.18

now

6000*1.5 = 9,000

6000*2 = 12,000

the last two are even lower

**Steve**, Thursday, May 22, 2014 at 1:02pmGood call, Damon. By rounding down to 90 I neglected the rather sizable underestimate of 2.47 by 2.00.
