Final answer:
The density of the granite is calculated using the mass of 6.725 kg (converted from 6725g) and the volume of 2.5 m^3, resulting in a density of 2690 kg/m^3, which is option (a) and is consistent with the typical density of granite.
Step-by-step explanation:
To calculate the density of granite, we use the formula density = mass/volume. Given that the mass of the granite is 6725g (which we convert to kilograms as 6.725 kg to maintain standard units), and the volume is given as 2.5 m^3, the density can be calculated as follows:
Density = Mass / Volume
Density = 6.725 kg / 2.5 m^3
Density = 2.69 kg/m^3
Therefore, the average density of the granite is 2690 kg/m^3, which matches option (a).
This value is consistent with the typical density values for granite.
