A piece of lead having a mass of 143.5 g is placed in an empty graduated cylinder.
34.0 mL of water is then poured slowly and carefully into the same cylinder.
The final water level would then indicate the total volume of the materials in the graduated cylinder.
What is this total volume in millileters?

For this problem, you have to take advantage of the formula: density = mass / volume. Here you know the mass of the lead, you can Google(R) the density and get the volume. Just add this volume to the volume of water, and this will be the total volume.
density of lead: 11.34 g/cm^3 = 11.34 g/mL (Wikipedia.org)
volume of lead: 143.5g *(mL / 11.34g) = 12.65 mL lead
total volume: 12.65mL + 34.0mL = 46.65mL TOTAL

ok again you really need help
143.5g x 1mL/11.34g = 12.65mL +34mL=46.65mL
