Rectangular prism has a length of 9 in., a width of 4 in., and a height of 112 in. the prism is filled with cubes that have edge lengths of 12 in. how many cubes are needed to fill the rectangular prism? enter your answer in the box.

That is wrong I believe the answer is 27 cubes are needed.

I say this because 9*4=36* 1  1/2 is 54*1/2=27.

You got the fractions mixed up 112= 1  1/2   12=1/2!!

Hope this helped...For future pple.
