Question

If the average sale price of lignite coal is $19.51 per 2,000 lbs, a geology log has 3 layers of coal which add up to 3.65 meters of thickness in an area that is 478,218 square meters. What is the economic evaluation?

Answer 1

Answer:

price = $48433333.5

Explanation:

given data

average sale price = $19.51 per 2000 lbs

layer of coal = 3

add = 3.65 meter thickness

area = 478218 square meter

to find out

What is the economic evaluation

solution

we find first volume that is

volume = area × thickness

volume = 478,218 × 3.65

volume = 1745495.7 m³

and we know density that is 1290 kg/m³

so weight = volume × density

weight = 1745495.7 × 1290

weight = 2251689453 kg × 2.205 lbs

weight = 4964975244 lbs

so price for 4964975244 lbs is

price = $\frac{19.51}{2000}$ × 4964975244

price = $48433333.5
