Answer: 8320 cubes.
Step-by-step explanation:
1. Calculate the volume of the rectangular prism:
Where<em> l </em>is the lenght, <em>w</em> is the width and <em>h</em> is the height.
Substitute values.
(You can convert 3 1/4 to decimal by dividing the numerator by the denominator of the fraction and add this to the whole part: 3+0.25=3.25)
Then:
2. Calculate the volume of a cube:
Where <em>s</em> is the lenght of any side.
Then:
3. To calculate the number of cubes that are needed to fill the rectangular prism (which you can call <em>n) </em>, you must divide the volume of the prism by the volume of a cube. Then:
cubes
