Question

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

Answer 1

40 cubes

Explanation:

We need to determine the volume of the cuboid.

`Volume=lbh`

We substitute the given dimensions l=2.5cm,w=2cm and h=1cm.

`Volume=2.5*2*1cm^3`

`Volume=5cm^3`

The volume of the cube is
`Volume =((1)/(2))^3=(1)/(8) cm^3`

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;

`(5)/((1)/(8) )=8* 5=40`
