Question

His parcel is a cuboid with dimensions 10 cm, 20cm and 40 cm. 20 cm 10 cm 40 cm to scale He looks at the prices of two companies, WeDeliver and GoParcels. Not drawn WeDeliver Total cost: Sum, in cm, of the 3 dimensions * £0.80 Find the cost of sending the parcel with each company. Give each of your answers

Answer 1

Explanation:

224 56

Answer 2

For WeDeliver= $224

For GoParcels = $56

Explanation:

Since we are told his parcel is a cuboid with dimensions 10cm, 20cm, and 40 cm, it means the parcel consists of 4 edges of 10 cm, 4 edges of 20 cm, and 4 edges of 40 cm.

For WeDeliver, the Total Cost is:

Sum, in cm, of the dimensions x 0.80, which is, (10cm *4) + (20cm *4) + (40cm *4) = 280cm x 0.80 = $224. While

For GoParcels, the Total Cost is:

Total area, in
`cm^(2)`, of all 6 faces, x .02

Remember that a cuboid has six (6) faces or sides, so the total area would be gotten by taking note of the length of each visible side of the parcel and then multiplying to get the other side after which we sum after doing so we get:

1. 
   `800^(cm2)` for front side
2. 
   `800^(cm2)` for the backside
3. 
   `400^(cm2)` for the top
4. 
   `400^(cm2)` for the bottom
5. 
   `200^(cm2)` for the left side
6. 
   `200^(cm2)` for the right side.

Total area =
`2,800^(cm2)` * 0.02 = $56
