WeDeliver = 640£

GoParcels=  56£

Step-by-step explanation:

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

length * wide * height = 20cm * 10cm  * 40cm= 800cm³

If the cost is £0.80 every, the cost will be: 800 * £0.80/ = 640£

The cost of GoParcels service depends on the area of the parcel. Since the parcel is cuboid, the area of the parcel will be:

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

2(20cm*10cm) + 2(20cm * 40cm) + 2(10cm*40cm)= 2800 cm²

If the cost is  £0.02/cm^3, then the cost will be:

2800cm² *  £0.02/cm² = 56£
