Magnification size ÷ real actual size
Webeyepiece lens magnification x objective lens magnification = total magnification. x10 x x40 = x400. Step 2: Calculate the image size in the units asked for (micrometres) 1 mm = 1000 μm. 3 mm = 3000 μm. Step 3: Calculate the actual size of the red blood cell. Therefore, the average size of a red blood cell in this sample is 7.5 micrometres WebFirst, we rearrange the formula to make actual size the subject: Actual size = Image size ÷ Magnification. Then, we divide the image size by the magnification to get the actual size: Actual size = 8cm ÷ 20,000 = 0.0004cm. Finally, we convert from cm to µm: 0.0004cm = 4µm. The actual length of the bacterial cell is 4µm.
