A ruler. Measure one of the sides, and take that measurement times itself three times, and you'll have the volume.
The answer depends on the size of the cube: it could be a micrometre, vernier callipers, a ruler, a tape measure.
All you need is a graduated ruler to measure the length of one edge. From there one calculates the volume. For a cube, which has edges of equal length, you can find the the volume by cubing the length of an edge. Vcube = e3
Yarn , because that can rap around the cube OR you could use stringy ruler type thing
Scales to measure its mass and a ruler to measure the length of the cube's side.

The measure of the edge of a cube that has a volume of 729 inches to the third is: 9 inches.
To find the density you need the mass and volume and then, density = mass/volume. Given a ruler, you can easily measure an edge of the cube. If that is x units, then the volume is x3 cubic units. However, it is not clear how you find a mass with just a balance. You need some standard weights, but these do not appear to be provided. You are stuck and cannot answer the question.
I think that the most commonly used tool to measure the height of a cube is an everyday ruler.
You would need a balance to measure its mass. You would need a ruler to measure the length of its sides. Then you would need to calculate volume. Then divide the mass by the volume to get density.
The volume of a 3-inch cube is 27 cubicinches. (not "inches")
Volume
The volume of a cube whose sides measure four inches is: 64 cubic inches.
