Answer: 3 kg 605 g
Step-by-step explanation:

Multiply both parts of the equation by V:
![m=\rho V\\\\=1.03*3.5\\\\=3.605\ kg](https://tex.z-dn.net/?f=m%3D%5Crho%20V%5C%5C%5C%5C%3D1.03%2A3.5%5C%5C%5C%5C%3D3.605%5C%20kg)
Answer:
0.3*0.3*0.3*0.3=0.3⁴
0.2*0.2=0.2²
0.3×0.3×0.2×0.2×0.3×0.3 = 0.3⁴ * 0.2²
