Find the volume of each pyramid. Round to the nearest tenth if necessary.

Don't worry about the other stuff above the question. It has nothing to with the 2 questions below themselves.

they used 313 gallons of paint

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
