How many cubes with sides length of 1/2 cm does it take to fill the prism

Answer:
40 cubes
Step-by-step explanation:
We need to determine the volume of the cuboid.
[tex]Volume=lbh[/tex]
We substitute the given dimensions l=2.5cm,w=2cm and h=1cm.
[tex]Volume=2.5\times2\times1cm^3[/tex]
[tex]Volume=5cm^3[/tex]
The volume of the cube is [tex]Volume =(\frac{1}{2})^3=\frac{1}{8} cm^3[/tex]
We need to divide the volume of the cuboid by the volume of the cube to get the number of cubes that can fill it;
[tex]\frac{5}{\frac{1}{8} }=8\times 5=40[/tex]
