Determine the number of cans for the wall
The dimension of the wall is not given. So, I will use the following assumed values:


First, calculate the area of the wall



If 
Then 
Cross Multiply:



Make x the subject


400 cans using the assume dimensions.
So, all you need to to is, get the original values and follow the same steps

Step-by-step explanation:
length does not mean anything in terms of diameter
The required scale model will be 1:6.24 10^9
<h3>Finding scale factors</h3>
A scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.
Given the following parameters
Distance of sun to Jupiter = 7.8 * 10^8 km
If the distance of sun to Jupiter is 8m on his scale, hence the value of n is calculated as;
n = 8 * 7.8 *10^8
n = 62.4 * 1068
n = 6.24 10^9
Hence the required scale model will be 1:6.24 10^9
