Computer Shipments
Nell Computers wants to hire Overnite Delivery Service to truck computers from the warehouse to stores. Overnite has 2 trucks - 1 large and 1 small. The large truck is twice as high, twice as wide, and twice as long as the small one. Overnite has decided to charge $500 per shipment for each delivery made with a fully loaded small truck.
Assuming that charges are based on each truck's volume, what should Overnite charge for each delivery made with a fully loaded large truck?

Hint
It's not $1,000!Answer
Overnite Delivery Service should charge $4,000 for a large truckload.Since each dimension of the large truck (height, width, and length) is twice that of the small truck, the volume of the large truck is 8 times that of the small truck. So, for a large truckload, Overnite should charge 8 times the price of a small truckload. That's 8 * $500, or $4,000.

1st, doubling to the 3rd power and getting octupled volume was very obvious. 2nd, a driver will not be getting 8 times the wage he gets for driving the smaller truck. 3rd, it is unlikely the big truck will cost 8 times as much as the small one. After all, its shell should only require about 4 times the steel etc.
Very nice, stated $ourDough to me!

don't like it
I liked it! Made me think.
In addition to Stil's comments I doubt you'll find two delivery trucks with one half the width as the other.
