Question

A gold bar has dimensions 1.5 inches by 4 inches by 9.2 inches. What is the mass of
the gold bar in grams? Kilograms? Recall the density of gold is 19.3 g / cm^3, and there
are 2.54 cm in 1 inch.

Answer 1

Answer:

17458.12 gm     ( or 17. 45812 kg )

Explanation:

Find volume in in^3   then convert to cm^3  and multiply by density

1.5  x   4   x   9.2 =55 .2 in^3

   convert this to cm^3 :   55.2  * 2.54^3 = 904.566 cm^3

904.566 cm^3 * 19.3  g /cm^3 = 17458.12 gm
