a)
To find: The scale if actual height of the statue of Zeus is given as 40 feet when its height on scale model is given as 8 inches. Also to find the required scale factor between two heights.
a)

Answer to Problem 26SR
Scale on scale model is 1 inch
Explanation of Solution
Given information:
The height of the statue of Zeus on scale model is 8 inches and its actual height is 40 feet.
Concept used:
Scale is actually a comparison between two quantities, that results the one unit of one quantity equals to how much unit of second quantity. Also, scale factor is the ratio between two corresponding given quantities. It is also used the following conversion formula:
1 feet
Calculation: On comparing two given quantities ,
So,
Based on above calculation, the applied scale is 1 inch= 5 feet.
b)
To find: The scale if actual height of the statue of Zeus is given as 40 feet when its height on scale model is given as 8 inches. Also to find the required scale factor between two heights.
b)

Answer to Problem 26SR
Scale factor required is 1:60 or 60 only.
Explanation of Solution
Given information: The height of the statue of Zeus on scale model is 8 inches and its actual height is 40 feet.
Concept used:
Scale is actually a comparison between two quantities, that results the one unit of one quantity equals to how much unit of second quantity. Also, scale factor is the ratio between two corresponding given quantities. It is also used the following conversion formula:
1 feet= 12 inches
Calculation: As 40 feet
So scale factor required
Based on above calculation, required scale factor is 1:60.
