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

svp [43]

Answer:

The Total amount of of 33 boxes of chocolates including taxes is $838.358

Step-by-step explanation:

Given as :

The sales tax rate for city = 4.306%

The sales tax rate for the state = 44%

Total number of boxes = 33

The price of each chocolates = $17.13

So , The price of 33 boxes of chocolates = $17.13 × 33

I.e The price of 33 boxes of chocolates = $565.29

Now total tax including state and city =  4.306% + 44% = 48.306 %

So, The tax amount paid for 33 boxes of chocolates = 48.306 % of $565.29

∴    The tax amount paid for 33 boxes of chocolates = 48.306 % × $565.29

                                                                       = 0.48306× $565.29

                                                                       = $273.068

∴ The Total amount of of 33 boxes of chocolates including taxes = $565.29 +  $273.068 = $838.358

Hence The Total amount of of 33 boxes of chocolates including taxes is $838.358 . Answer
