Question

Answer 1

See below.

Explanation:

It depends on what information is provided in the problem. The units are the key in deciding how to solve these types of problems. The cost could be given as: (using metric, but foot or other unit of length may be substituted):

• $/m for each type of board,
• $/m^2 for plywood
• $/m^3 for bulk purchases
• Other units may be based on mass/weight, etc.

These prices are all conversion factors. You can convert a measure such as length, volume, mass, etc., to cost by choosing the correct unit for the measure given. Use the conversion factors in a manner that when some of the units cancel, you are left with the desired unit.
