Question:
Following figure shows a fossil of footprints made by an anthracosaur, an amphibian from the Upper Carboniferous. We can calculate the magnification of this image because we know that the scale bar (black and white strip) measures 1 inch long with a value of 10.5 cm (each stripe on the bar is 5 mm wide). By doing the calculations below, we can conclude that this image is about one-fourth its actual size.
Magnification = scale bar length/scale value
Magnification = 1 inch/10.5 cm
Magnification = 2.54 cm/10.5 cm
Magnification = 0.24?
