Answer:
Step-by-step explanation:
Density of copper = 9.86 g / cm^3 = 9860 kg / m^3
= 9.86 x 1 / 1000 kg / cm^3 = 9.86 / 1000 Kg / cm^3
= 0.00986 kg / cm^3
= 9.86 x 1 / 1000 kg (1 / 100 m)^3
= 9.86 x 1000000 / 1000 kg / cm^3
Mass "m" = 9860 kg / m^3
thus the mass of copper in solid form is m = 9860 kg / m^3
If you're talking about the red shaded part, the answer is 8
Alright, so 9^(-1/2) would mean that we have 1/(9^(1/2)). Since 9^(1/2) is the square root of 9 (1/3 would be the cube root, etc.), we have 1/sqrt(9)=1/3. For 3/(1/3), we have (3/1)/(1/3), which is (3/1)*(3/1)=9. Squaring 9, we get the cube root of 81 which is around 4.3
