Boxes have edges of 4 inches, 12 boxes are put in and completely fills the cartoon, what is the volume of the carton?

So what I think is that you multiply 4 by 4 or add 4 four times.Then, you would multiply 16 with 12 because there are 12 boxes and each box is 16. After doing that, you will get 192. Hope it helps :)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
