640 = 8x
80 = x
Thus, the height of the lighthouse is 80 feet tall.
They are essentially asking us to solve:
Solving this equation for x tells us that it will take around 80.1 years for the materials in the vault to reduce to 357 pounds.
2 ounces
using the conversion
1 pound = 16 ounces ⇒ 
= 8 ounces
Divide 8 by 4 to calculate amount for each cone
amount = 8 ÷ 4 = 2 ounces
