# Cuboids over 2D images

While cuboids are inherently 3D objects, you can draw a cuboid with different front and back faces over 2D images in Mindkosh.

To do this, first make sure you've selected the Cuboid tool when creating the task. On the annotation screen, select the cuboid tool.

<figure><img src="/files/HY5Z5YRZzZj5vC2F2MBP" alt=""><figcaption></figcaption></figure>

Then draw the cuboid by drawing the *Front* face of the object just like you would draw a 2D bounding box - simply Click on one corner of the face and drag the mouse over to the opposite corner.

<figure><img src="/files/Ndx6VNw15ao3uMLfgoz4" alt=""><figcaption></figcaption></figure>

This will result in a cuboid with the front face as drawn by you and a parallel, similar sized back face.

The faces can be moved individually by clicking over each face and moving them to the desired location. You can also adjust the width of the back face. However, as you can see from the image above, you can only adjust one side of the back face. The height of both front and back faces is locked and stays the same.
