Step-by-step explanation:

Alright, so we have the city that needs 800 cubic feet of salt. And then we have this truck, which will transport the salt.

We know that this truck's volume is the amount of salt it could carry in one trip, so let's solve for the truck's volume.

The volume of a rectangular prism is v=lwh, so we can multiply 4 by 8 by 6. 4 times 8 is 32, and 32 times 6 is 196. So now we know that the amount of salt this truck can carry in one trip is 196.

196/1

So we need 800. We can then do an equivalent fraction:

=

196x=800(1)

196x=800

800/196 is approximately 4.08.

To find the number of trips the truck will need to make, We need to round up so that we don't fall short.

The number of trips is 5.
