step 1 measure the length of the cell structure image on the micrograph in centimetres
step 2 measure the length of the cell structure image on the micrograph in millimetres
step 3 divide the image length by 1000
step 4 multiply the image length by 1000
step 5 divide by 8
step 6 multiply by 8
Options
A steps 1, 3 and 6
B steps 1, 4 and 6
C steps 2, 3 and 5
D steps 2, 4 and 5
