Answer:
Work done
lb-ft
Step-by-step explanation:
The density of the chain in lb/ft is equal to
lb/ft
Total Work done is equal to the summation of work done up to the top of building.
We will use integration for this evaluation.
The mathematical relation is as follows
![\int\limits^{40}_0 {X} \, pdx](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7B40%7D_0%20%7BX%7D%20%5C%2C%20pdx)
where "p" is the density
Substituting the given values, we get
![\frac{95}{27} \int\limits^{27}_0 {X} \, dx\\\frac{95}{27} X^2\int\limits^{27}_0\\ \frac{95}{27} {27^2 - 0^2}\\\frac{95}{27} * 27 * 27\\95* 27\\= 2,565](https://tex.z-dn.net/?f=%5Cfrac%7B95%7D%7B27%7D%20%5Cint%5Climits%5E%7B27%7D_0%20%7BX%7D%20%5C%2C%20dx%5C%5C%5Cfrac%7B95%7D%7B27%7D%20%20X%5E2%5Cint%5Climits%5E%7B27%7D_0%5C%5C%20%5Cfrac%7B95%7D%7B27%7D%20%20%7B27%5E2%20-%200%5E2%7D%5C%5C%5Cfrac%7B95%7D%7B27%7D%20%20%2A%2027%20%2A%2027%5C%5C95%2A%2027%5C%5C%3D%202%2C565)
Work done
lb-ft
What is this? may I ask? did you mean to attach a photo?
9.5 per square yard.
since total square yard is 12, 9.5 × 12 (per 1 × 12 square yard.)
so 9.5 × 12 = $114.
