Question

2 instead of using cubic units to measure volume, cristobal wants to measure volume using boxes of pencils. what is the volume of this rectangular prism using boxes of pencils as the unit of measure?

Explanation:

Step1: Count the number of pencil - boxes along the length, width and height.

Let's assume the number of pencil - boxes along the length is $l$, width is $w$ and height is $h$. By observing the figure (assuming we can count the boxes), if $l = 4$, $w=2$ and $h = 3$.

Step2: Use the volume formula for a rectangular prism.

The volume $V$ of a rectangular prism in terms of the number of units (pencil - boxes here) is given by $V=l\times w\times h$. Substituting the values, we get $V = 4\times2\times3$.
$V=24$

Answer:

24 boxes of pencils
