Answer:
The number of cubes that fill the prism is 24
Step-by-step explanation:
Given as :
The length of cube (l) = cm
The length of prism (L) = 1 cm
The width of prism (w) = 2 =
cm
The height of prism (h) = cm
Let the number of cubes that fill the prism = x
Now, Volume of cube with length (l) = l³ cm³
Or, Volume of cube with length (l) = cm³
Or, Volume of cube with length (l) = cm³
Again , Volume of prism =
Or, Volume of prism =
Or, Volume of prism = cm³
<u>So , The number of cubes to fill prism </u>
The number of cubes × Volume of cube = Volume of prism
Or, x × cm³ =
cm³
or x = = 24
Hence The number of cubes which fill the prism is 24 Answer
