An object whose volume is 125cm^3 was enlarged to an image whose volume is 100cm^3. Find the scale.
The scale factor can be found using the formula:
scale factor = (image size)/(original size)
In this case, the image size is given as 100 cm^3 and the original size is given as 125 cm^3. Therefore:
scale factor = 100/125
scale factor = 0.8
So the object was enlarged by a factor of 0.8 or scaled down by 1.25.
To find the scale, we can use the formula:
Scale = (Image volume) / (Original volume)
Given that the image volume is 100 cm^3 and the original volume is 125 cm^3, we can substitute these values into the formula:
Scale = 100 cm^3 / 125 cm^3
Simplifying the expression:
Scale = 0.8
Therefore, the scale is 0.8 or 80%.
