Determine 82012

There is a 30 cm layer of sand in the landing area. Determine the width of the landing pad if its length is 5 m and the volume of sand in it is 2.7 m³.

Correct answer:

c =  1.8 m

Step-by-step explanation:

$$\begin{gathered} a=30\text{cm}\to \text{m}=30:100\text{m}=0.3\text{m} \\ b=5\text{m} \\ V=2.7{\text{m}}^3 \\ V=a\cdot b\cdot c=abc \\ c=\frac{V}{a\cdot b}=\frac{2.7}{0.3\cdot 5}=1.8\text{m} \end{gathered}$$
