Answer 8

(3 x 4.5) x 6 = 81 cm³
Now, we need to work out the volume of one of the little cubes, found by raising the side length to the power of 3
0.5³ = 0.125 cm³

Now, all we have to do is divide the larger volume by the smaller volume to find the number of cubes we need to fill the prism up.
81/0.125 = 648 cubes

Answer 9

^your answer^

Answer 10

(3 x 4.5) x 6 = 81 cm³
81/0.125 = 648 cubes
