To calculate the number of squares that can be cut from the card, we need to determine how many rows and columns of 5cm squares can fit within the dimensions of the card. For a 20cm by 40cm card, we can fit 4 rows of 5cm squares along the 20cm side and 8 columns of 5cm squares along the 40cm side. Therefore, a total of 4 rows x 8 columns = 32 squares can be cut from the card.
55cm x 40cm x 20cm = 21.65 inches x 15.75 inches x 7.87 inches.
55cm x 40cm x 20cm = 21.65inches x 15.75inches x 7.87inches1 inch = 2.54cm55cm = 55cm * 1 inch/2.54cm =21.65 inches40cm = 40cm*1 inch/2.54cm=15.75inches20cm = 20cm*1 inch/2.54cm=7.87inches

there are 55 squares in the bingo card
Well, darling, 55cm x 40cm x 20cm equals 44,000 cubic centimeters. In English, that's about 2,682.05 cubic inches. So, if you're looking to pack a box or something, you better make sure it fits within those dimensions!

The easiest way to reason this is to consider how you could connect nine squares together while leaving the largest amount of perimeter exposed. In other words, what's the largest number of faces you can leave exposed on a set of squares that are all connected? The answer is that if you connect all of the squares in a line, then the two end squares will have three faces exposed and the other seven squares will have two faces exposed. That gives you 2 * 7 * 2cm + 3 * 2 * 2cm = 28cm + 12cm = 40cm. So the maximum perimeter you can get is 40cm. There are many other ways that you can arrange the squares to give you the same perimeter (eg. a plus sign, a zig-zag, and so on), but none that will give you more.
