A prism's volume is the area of the face that does not have more than 1 equal counterpart mulitplied by the height of the entire prism, in which the height of the prism is not any of the sidelengths of the face whose area is being multiplied.

To compare the displayed Wright flyer in the museum with the actual plane, we have to compute for the ratio of the corresponding parameter. In this item, for both the display and the actual plane, we are given with the length. Computing for the ratio gives us,
ratio = length of the model / length of the actual plane
Length of the model = 35 cm
We need to calculate for the length of the model in ft.
length of the model = (35 cm)(1 in/2.54 cm)(1 ft/12 in)
length of the model = 1.148 ft
Going back to the equation for the ratio,
ratio = (1.148 ft)/21 ft
ratio = 0.055
Hence, the dimensions used in the model is equal to 0.055 times the actual dimensions.
Error may occur because of the number of significant figures considered for rounding up or down of the answers after each calculation.
The number of multiples of 5 from 1 to 100 is:
1≤5n≤100
1/5≤n≤20, since n must be an integer
1≤n≤20
So the multiples of five number 20-1+1=20 elements, and the probability of choosing one of the multiples from the first 100 positive integers is:
P(5n)=20/100=1/5
