Question

The crew knows the amount of dirt the truck can hold each trip in cubic yards.

Answer 1

Given:

Measurements of hole are 48ft 39ft and and 9ft

Required:

Volume in cubic yd

total number of trip

total cost of trip

Step-by-step explanation:

First we need to convert given measurements from ft to yd

`\begin{gathered} 3ft=1yd \\ 48ft=16yd \\ 39ft=13yd \\ 9ft=3yd \end{gathered}`

A)

`V=lhw=16*13*3=624yd^3`

B)

11 cubic yd in 1 trip

then

624 cubic yd in x trip

`x=(624)/(11)=56.7\approx57`

C)

cost for 1 trip is $1175

then

cost for 57 trip is y

`y=57*1175=66975`

Final answer:

Volume in cubic yd is 624

total number of trips is 57

total cost of trip $66975
