the wood block measures 10 by 6 by 2 inches.
that would make the volume 10 * 6 * 2 = 120 cubic inches.

the block weighs 3 pounds 10 ounces.

the density is the mass divided by the volume.

3 pounds 10 ounces is equivalent to 16 * 3 + 10 = 58 ounces.

3 pounds 10 ounces is also equivalent to 3 + 10/16 = 3.625 pounds.

the density in pounds per cubic inch would be 3.625 / 120 = .03002083333 pounds per cubic inch.

the density in ounces per cubic inch would be 58/120 = .4833333333 ounces per cubic inch.

the density figures are equivalent.

take the density figure in pounds and multiply it by 16 and you will get the density figure in ounces.

take the density figure in ounces and divide it by 16 and you will get the density figure in pounds.
