Solution

First, we need to convert lbs to grams. We know that 1 lb = 454 g. So, we multiply the density by this conversion factor:

2.87 x 10^-3 lbs/inch^3 * 454 g/lb = 1.30318 g/inch^3

Next, we need to convert cubic inches to milliliters. We know that 1 inch = 2.54 cm, so 1 cubic inch = (2.54 cm)^3 = 16.387 mL. So, we divide the density by this conversion factor:

1.30318 g/inch^3 / 16.387 mL/inch^3 = 0.0795 g/mL

So, the density of the object is approximately 7.95 x 10^-2 g/mL.
