3 Sig figs because both measurements have three sig figs. In a lab setting, you would round to your least precise measurement. So its useless to use a meter stick and a high precision scale to take measurement because you have to use the amount of Sig figs for your least precise tool

80.1 g* (1 cm^(3)/ 2.70 g)= 29.666666... cm^(3).
The calculated volume should have 3 significant figures, so the final answer is 2.97*10^(1) cm^(3)
Hope this helps~
