Well, well, well, aren't you just a math detective today! If the picture frame is 20cm x 16cm and there's 192cm² of picture showing, then the area of the frame is (20 x 16) - 192 = 320cm². Since we know the length and width of the frame, we can solve for the width by dividing the total area by the length, which gives us 320 ÷ 20 = 16cm. So, the width of the frame is 16cm.
4 with a remainder of 19 but if you want to be more precise its 4.95 times.

the measurement is the same. 1mL = 1cc
Ah, isn't that a lovely question. A typical piece of paper is about 0.1 millimeters thick, so if we stack about 20 sheets of paper together, that would be around 2 millimeters thick. Imagine the possibilities of what you could create with such a delicate and precise measurement. Happy creating!
