Problema Solution

Suppose that your company makes plastic trays and its planning new ones with dimensions double those now being made. Your company president is convinced that they will need only twice as much plastic as the older version. "twice the size, twice the plastic" He proclaims, and no one is willing to challenge him. Your job is to make a presentation to the president where you tactfully point out that he is wrong and where you explain that the new trays will require eight times as much plastic. Prove that to president.

The formula of the current tray is  l*w* h

The formula of the broposed tray 2l*2w*2h

For example, if the first tray (a) is 10 * 5* 2 the area would be 100

The second tray, then, would be 20 * 10 * 4, making the area 800.
