PLEASE HELP/kinda easy maths but I don’t get it/I’ll give brainiest award thingy

The product of the dimension must be 16.

In the first line, you have 1*1*16=16.

In the second line, you have 1*2*8=16.

In the third line, you start with 1 again. So, you need two more numbers that give 16 when multiplied, which are not 2 and 8. You don't have many choices.. :)

Similarly, in the last line, you start with 2. This means that the two missing numbers must give 8 when multiplied, and they can't be 1 and 8 (already used in the second line). Again, there are not many options.

Try to work this out on your own!

C: 4, 4.

D: 1, 8. hope this helps:)

To figure this out, you would find the area of the book by doing 9 * 6, which is 54. Now what you do is multiply that by 1.5 since that is the scale factor, and you get 81 in²

I hope this helps you! If it does, please rate as Brainliest :D
