    Answer:

    Devin will need 9 cubes of wax.

    Step-by-step explanation:

    To find the volume of the pyramid, you use (area of the base)* height of the pyramid divided by 3. You know the volume of a cube of wax is 32 cm^3. The volume of your pyramid is 270 cm^3. 270/32=8.4375.

    Once you get 8.4375 cubes, you round to the next whole number, which is nine.
