Answer :
Final answer:
The cube's mass is approximately 4.149 kg.
Explanation:
The mass of the cube can be calculated using the formula:
Mass = Density x Volume
Here, the density is given as 6510 kg/m³ and the volume of the cube can be calculated as (25.1 cm)³.
The mass of the cube will therefore be:
Mass = 6510 kg/m³ x (0.251 m)³
= 4.149 kg
So, the cube's mass is approximately 4.149 kg.
