CSS 3D Cube Offsets

Question

I am trying to use CSS 3D transforms to display cubes and cuboids that will contain cross sections. I focus on Chrome, Firefox and MSIE 11. I found that to support MSIE 11 compatibility, I need to avoid using transform-type: preserve-3d, since this is not supported by Microsoft, so I need to apply all the parent and child transforms to each face of the cube .

For a cube, I can rotate each side to align them correctly, but for a cuboid, the ends are offset - why is this and how can I fix it?

This screenshot illustrates the problem:

Here is the HTML:

<div class="test test1">
    <h1>1.</h1>
    <div class="cube">
        <div class="side front">1</div>
        <div class="side back">6</div>
        <div class="side right">4</div>
        <div class="side left">3</div>
        <div class="side top">5</div>
        <div class="side bottom">2</div>
    </div>
</div>

<div class="test test2">
    <h1>2.</h1>
    <div class="cube cuboid">
        <div class="side front">1</div>
        <div class="side back">6</div>
        <div class="side right">4</div>
        <div class="side left">3</div>
        <div class="side top">5</div>
        <div class="side bottom">2</div>
    </div>
</div>

and here is the CSS:

    div.test {
        height: 200px;
    }

    /* basic cube */
    .cube {
        font-size: 4em;
        width: 500px;
        margin: auto;
        /* MSIE11 does not support preserve-3d.
          for MSIE all transforms must be applied to all elements */
    }

    .side {
        position: absolute;
        width: 100px;
        height: 100px;
        background: rgba(255,0,0,0.3);
        border: 1px solid black;
        color: white;
        text-align: center;
        line-height: 100px;
    }
    /* for MSIE11 compatibility, avoid using a transform on the parent, combine all parent+child transforms, transform-style: preserve3d is not supported */
    .front {
        transform: rotateX(-40deg) rotateY(32deg) translateZ(50px);
        z-index: 1000;
    }
    .top {
        transform: rotateX(-40deg) rotateY(32deg) rotateX(90deg) translateZ(50px);
        z-index: 1000;
    }
    .right {
        transform: rotateX(-40deg) rotateY(32deg) rotateY(90deg) translateZ(50px);
    }
    .left {
        transform: rotateX(-40deg) rotateY(32deg) rotateY(-90deg) translateZ(50px);
        z-index: 1000;
    }
    .bottom {
        transform: rotateX(-40deg) rotateY(32deg) rotateX(-90deg) translateZ(50px);
    }
    .back {
        transform: rotateX(-40deg) rotateY(-148deg) translateZ(50px);
    }

    /* cuboid - 100 x 100 x 200 */
    .cuboid .front {
        width: 200px;
    }
    .cuboid .top {
        width: 200px;
    }
    .cuboid .right {
        transform: rotateX(-40deg) rotateY(122deg) translateZ(150px);
    }
    .cuboid .back {
        width: 200px;
    }
    .cuboid .bottom {
        width: 200px;
    }
