Answer:
The truck will need to make 3 trips.
Step-by-step explanation:
First, we need to find the volume that the truck can carry. Using the dimensions of the truck and the volume formula, we have:
[tex]V=lwh\\V=8.5\times5\times3.5\\V=148.75\text{ ft}^3[/tex]
Since we need to move a total of 400 cubic feet, we will divide that amount by the truckload capacity (volume).
[tex]400 \div 148.75 \approx 2.689[/tex]
In context, he will need to take three truck loads: two loads will be full, and the third will not be full.
