Which is better a truck delivery of soil or doing it yourself.

Area to cover is 3500 SQ FEET with a 4 inch layer of topsoil or .33 =1156 cubic yards

Your truck bed Volume of truck 80/36=2.22*69/36=1.92*20/36=.555=2.34 cubic feet

1156 cubic feet / 2.34 cubic feet= 494.01 or 494 truck loads * gas 4.01= 1981.00

on large mac truck load holds 18 cubic yards *27 cubic feet =486 cubic feet per truck load.

1156 cubic feet / 486 cubic feet =2.37 truck loads for yard
Soil cost is $30.00 per truck load plus $18 per cubic yard and there is 18 cubic yards per load

18*18= $324 + $30.00= $354.00 per truck load $354.00 8 2.37 loads= $838.98 total cost for the delivery.

gas 9/17=.53*3.79per gallon = 2.00 * 2 trips =4.01 per trip

Not sure this is right please help

Most of it looks good - I've pasted your work below

--> with a few corrections

Area to cover is 3500 SQ FEET with a 4 inch layer of topsoil or .33 =1156 cubic yards
--> 3500 × (1/3) = 1166.67 cubic feet
-->1166.67 / 27 = 43.2 cubic yards

Your truck bed Volume of truck 80/36=2.22*69/36=1.92*20/36=.555=2.34 cubic feet
--> should be 2.37 cubic yards

1156 cubic feet / 2.34 cubic feet= 494.01 or 494 truck loads * gas 4.01= 1981.00
--> 43.2 cubic yards / 2.37 cubic yards = 18.2 or ~18 truck loads * gas 4.01 = 72.18

on large mac truck load holds 18 cubic yards *27 cubic feet =486 cubic feet per truck load.
--> math is correct, but might as well leave it as 18 cubic yards, since everything else is in cubic yards

1156 cubic feet / 486 cubic feet =2.37 truck loads for yard
--> 43.2 cubic yards / 18 cubic yards = 2.4 truck loads

Soil cost is $30.00 per truck load plus $18 per cubic yard and there is 18 cubic yards per load
--> ok

18*18= $324 + $30.00= $354.00 per truck load $354.00 8 2.37 loads= $838.98 total cost for the delivery.
--> 354.00 × 2.4 = $849.60

gas 9/17=.53*3.79per gallon = 2.00 * 2 trips =4.01 per trip
--> is this the cost per trip for the big truck? I noticed you also used 4.01 for the smaller truck - its gas should be cheaper per trip.

--> overall, good work. just be careful not to over-round answers that will be used in follow-on calculations; also be consistent with units.

To compare the options of truck delivery of soil versus doing it yourself, we need to consider factors such as cost, convenience, and personal preference.

For the truck delivery option:
1. Calculate the total amount of soil needed: 3500 square feet * 4 inches (0.33 feet) = 1156 cubic feet.
2. Determine the volume of your truck bed: Assuming the bed volume is 80 inches long, 36 inches wide, and 20 inches deep, we can convert it to cubic feet: (80/36) * (69/36) * (20/36) ≈ 2.34 cubic feet.
3. Calculate how many truckloads are required: 1156 cubic feet / 2.34 cubic feet = 494.01 (rounding up to 494 truckloads).
4. Consider the cost per truckload: Assuming each truckload holds 18 cubic yards (486 cubic feet) and calculating the cost of each load: $18 (cost per cubic yard) * 18 cubic yards + $30.00 (truckload fee) = $324 + $30.00 = $354.00.
5. Calculate the total cost for the truck delivery: $354.00 per truckload * 2.37 (trucks needed) = $838.98.
6. Consider the cost of gas for the delivery trips: Assuming gas costs $3.79 per gallon and the truck makes two trips, calculate the total cost: 9/17 (gas mileage) * $3.79 (cost per gallon) = $2.00 (cost per trip) * 2 (trips) = $4.01.

For the DIY option:
1. Calculate the total amount of soil needed: 3500 square feet * 4 inches (0.33 feet) = 1156 cubic feet.
2. Determine the amount of soil a large truckload can hold: Assuming a large truckload can hold 18 cubic yards (486 cubic feet).
3. Calculate how many truckloads are required: 1156 cubic feet / 486 cubic feet = 2.37 (rounding up to 3).

Comparing the costs:
- Truck delivery cost: $838.98 + $4.01 (gas cost) = $842.99.
- DIY cost: 3 truckloads * $354.00 = $1,062.00.

Based on cost alone, the truck delivery option is more affordable in this case. However, there are other factors to consider such as convenience, effort required for DIY, availability of delivery services, and personal preference.
