Reshaping 3D function to 2D

Write the function RepTile() that accepts a 2x2x2 array as input. Then transforms that input into a 2x4 array. And it tiles the 2x4 array 3 times vertically and twice horizontally. The resulting 6x8 array is its output

So far I have the follow code. Im getting a "Error using reshape. To RESHAPE the number of elements must not change"

function [myRepTile] = RepTile(mxtrx2)

    tmp = reshape(mxtrx2,[2 4]);
    tmp = repmat(mxtrx2,[3 2]);
    myRepTile = tmp;
end
