Granite sidewalk

On the sidewalk, 3 m wide and 8 m long, 2 m³ of mosaic stone (granite cubes) was used. The master of tiles had to pave the sidewalk 2.5 m wide and 65 m long. How much m³ of the stone does it consume?

Correct answer:

V =  13.5417 m³

Step-by-step explanation:

$$\begin{gathered} h=2/(3\cdot 8)=\frac{1}{12}\doteq 0.0833\text{m} \\ a=2.5\text{m} \\ b=65\text{m} \\ V=a\cdot b\cdot h=2.5\cdot 65\cdot 0.0833=13.5417{\text{m}}^3 \end{gathered}$$
