let n represent number of blocks

let m represent weight of 1 block but in pounds because we want to express our total weight in pounds.

if n is number of blocks and m mass of one block, mass of n blocks would be
n*m

that means that conversion factor is m ---> weight of 1 block in pounds

The correct answer is:


The conversion factor would be the number of blocks multiplied by the weight of 1 block.


Explanation:


Consider the following example:

Suppose 1 block weighs 3 pounds. If there are 15 blocks, to find the total weight of the blocks, we multiply 3 by 15: 3(15) = 45. This means the total weight would be 45 pounds.


For any given number of blocks and any given weight of 1 block, to find the total weight of the blocks we would multiply the number of blocks by the weight of 1 block.
