Hello!

We first have to find the volume of the rectangular prism

To find the volume we use the equation lwh

l is length
w is width
h is height

Put in the values

12 * 5 * 4 1/4 = 255

Now we have to find the volume of one cube

the volume of a cube is a cubed

a is a side of the cube

1/4 cubed is 1/64 or 0.015625

Now we divide this by the volume of the rectangular prism

255 / 0.015625 = 16320

The answer is 16320

Hope this helps!
