WeDeliver = 640£

GoParcels=  400£

Step-by-step explanation:

The cost for WeDeliver service is calculated based on volume. The parcel is cuboid, so the volume will be:

length x wide x height = 20cm * 10cm  * 40cm= 800

The cost is £0.80 every , then the total cost will be: 800 * £0.80/ = 640£

The cost for GoParcels service is calculated based on the area of the parcel. Using the cuboid area formula, the area of the parcel will be:

2(length x wide) + 2(length x height) + 2(wide x height)=

2(20cm*10cm) + 2(10cm * 40cm) + 2(10cm*40cm)= 2000 c

The cost is  £0.02 every cm^3, then the total cost will be:2000 *  £0.02/ = 400£
