A pure sample of gold has a density of 19.4 g/cm3. The dimensions of a gold bar that you have been given are 3 inches by 5 inches by 2.5 cm. What is the weight of the gold bar in cubic inches? 1 in = 2.54cm Round your answer to the nearest tenth and don't add any units.

The answer to your question is 46 N (The weight is not measured in volume units, its units are of force).

Step-by-step explanation:

Data

density = 19.4 g/cm³

dimensions = 3 in x 5 in x 2.5 cm

1 in = 2.54 cm

Process

1.- Convert the dimensions to cm

                   1 in 2.54 cm

                   3 in x

                    x = (3 x 2.54) / 1

                    x = 7.62 cm

                   1 in 2.54 cm

                   5 in x

                   x = (5 x 2.54) / 1

                   x = 12.7 cm

2.- Calculate the volume of the bar

Volume = 12.7 x 7.62 x 2.5

             = 241.84 cm³

3.- Calculate the mass

 density = mass / volume

mass = density x volume

mass = 19.4 x 241.84

         = 4693.54 g

4.- Calculate the weight

  weight = mass x gravity

              = 4.7 x 9.81

              = 46 N

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
