The prism is filled with cubes that have edge lengths of
cm.
How many cubes are needed to fill the rectangular prism?
​

Answer 1

if they have sides of 1, its 810

Explanation:

we find the volume of the prism by using formula l x h x w

we plug it in 6 x 45 x 3. this equals 810. if the cubes have sides of 1, we do 1 x 1 x 1 to get the volume one, divide it from 810 to get 810 .
