I'm doing a science project that requires me to put sand in a jar to represent the inner layers of the Earth

On the directions it says to Multiply the depth of the jar, 16.5 cm, by the percent you calculated for the inner core to determine the depth, in centimeters, for each layer.

I got 20.01% for the inner core but when you multiply 16.5 x 20.01 = 330.165 is the answer. The jar is only 16.5 cm deep the answer can't be that the inner core is 330.165 cm.

Am I doing something wrong? Or not seeing something?

20.01% = 0.2001

16.5 x 0.2001= 3.30165

3.3 cm

Thank you!

It seems like there might be a mistake in the instructions or the calculations. Let's double-check the calculations and see if there's an error.

To determine the depth of each layer in the jar, you need to multiply the depth of the jar (16.5 cm) by the percentage for each layer.

In this case, you calculated the inner core to be 20.01%. To find the depth of the inner core, you should multiply 16.5 cm by 0.2001 (20.01% as a decimal).

16.5 cm * 0.2001 = 3.303 cm

So, based on your calculations, the depth of the inner core should be approximately 3.303 cm, not 330.165 cm.

It appears that there was an error in the calculation when you multiplied by the percentage. Please double-check your calculations and make sure you are using the decimal representation of the percentage.

It looks like there might be a misunderstanding in the calculation. Let me explain how to correctly determine the depth of each layer using the given information.

To represent the inner layers of the Earth in your jar, you need to determine the depth of each layer based on the percentage you calculated for the inner core. Here are the steps you should follow:

1. Convert the percentage to a decimal by dividing it by 100. In this case, you calculated the inner core's percentage as 20.01%, so the decimal equivalent is 0.2001.

2. Multiply the depth of the jar, which is 16.5 cm, by the decimal you just calculated (0.2001). This will give you the depth of the inner core layer in centimeters: 16.5 cm x 0.2001 = 3.302665 cm.

It seems like you made a decimal point error when performing the multiplication. The correct answer for the depth of the inner core layer should be approximately 3.3 cm, not 330.165 cm.

Remember to repeat these steps for each layer in your project by multiplying the decimal percentage by the jar's depth. This will allow you to determine the depth of each layer accurately.
