45cm
450 mm = 45 cm
1 cm = 10 mm therefore the shelf is 450mm 450mm/9mm = 50 books
450mm x 300mm 45cm x30cm 1350cm
To determine how many 450mm flags can fit in a 20ft x 20ft area, first convert the dimensions to millimeters: 20ft is approximately 6096mm, so the area is 6096mm x 6096mm. The area of one 450mm flag is 450mm x 450mm, which equals 202,500mm². Dividing the total area (37,184,256,000mm²) by the area of one flag gives approximately 183,000 flags that can fit in that space, assuming no gaps between flags.
