To find: The ratio of surface area and volume of model of car.
Answer to Problem 22HP
Ratio of surface area = 1:4
Ratio of volumes = 1:8
Explanation of Solution
Given: A model of car is given.
Let the scale factor of model of car is 1:24.
The dimension of model of car is 3 in high, 2.5 in wide and 6.5 in long.
Now find the ratio of surface and volume of the model of car.
First find the surface area of model of car
Now find the surface area of actual car
Now find the ration model to actual surface area is 1:4
Now find the volume of car model
Volume of actual shape of car
The ratio of volume of model to actual volume of car is 1:8
