Asmall bar of gold measures 40 mm by 25 mm by 2 mm. one cubic millimeter of gold weighs about 0.0005 ounce. find the volume in cubic millimeters and the weight in ounces of this small bar of gold.

I'm believing that you have the measurements in the right order, lwh, the Volume would be 5,000. You'd take 40 x 25 x 2= 5,000.

The weight is 2.5 oz. You get this answer by taking the Volume, 5,000, and multiply it by 0.0005 and you get 2.5 ounces.

I hope this helps!

Idon't know the answer
