This is easy. It's all about the formula density=mass/volume. First, calculate the volume:

2.9 cm x 3.6 cm x 10.0 cm = 104.4

(a) volume of the block is 104.4 cm^3.

Now that you know the volume and mass was given to you, calculating density is simple. Mass/volume, so 705/104.4=6.75

(b) the density of the block is 6.75 g/cm^3.
