The number of trucks needed is an illustration of rates
The number of trucks needed is 42
The size of the backfill is given as: 243 CY
A truck can load up to 162 CF
So, the number of trucks needed is calculated as:
[tex]n = \frac{243 CY}{162 CF}[/tex]
Convert CY to CF
[tex]n = \frac{243 * 27CF}{162 CF}[/tex]
Solve
[tex]n = 40.5[/tex]
Approximate
[tex]n = 41[/tex]
Hence, 41 trucks are needed
