Marguerite is building a box. she needs 78 pieces of wood that are 29 cm long. the wood comes in boards that are 6 meters long. how many boards will she need

First, we are going to multiply the pieces of wood by the length of each piece to find the total length she will need:


Next, we are going to convert 2262 centimeters to meters. To do that we are going to take advantage of the fact that 1 m=100cm:


Now, we just need to divide the total length of wood Marguerite needs by the length of each board of wood:

Since she will need full boards of wood, we must round 3.77 to its nearest integer 4.

We can conclude that Marguerite will need 4 boards of wood.
