Question

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

Answer 1

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

`78*29cm=2262cm`

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:

`2262cm* (1m)/(100cm) =22.62m`

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

`(22.62m)/(6m) =3.77`
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.
