The width of the well with the masonry should be 1.8 m. How much will digging a well 16 m deep be paid if an average of 800 CZK is paid from meter cubic?

Correct answer:

x =  32572.03 Kc

Step-by-step explanation:

$$\begin{gathered} D=1.8\text{m} \\ h=16\text{m} \\ r=D/2=1.8/2=\frac{9}{10}=0.9\text{m} \\ V=\pi \cdot r^2\cdot h=3.1416\cdot 0.9^2\cdot 16\doteq 40.715{\text{m}}^3 \\ x=800\cdot V=800\cdot 40.715=32572.03\text{Kc} \end{gathered}$$
