you would actually take the total thickness which is 1.85cm and divide that by how many cards are in the stack, so your answer would be 1.85/55
To find the answer, take 55 and divide it by 1.85 to get the thickness of one card. In this case the answer would be 29.72973 cm. each.
To find the thickness of one business card, divide the height of the stack (1.85 cm) by the number of cards (55). This results in a thickness of about 0.03 cm per card. This calculation helps us understand the individual size of each card in the stack.
