The outside surfaces of a cereal box are printed with text and pictures. what is the print area (surface area) of a box that is 2 inches wide, 8 inches long, and 10 inches tall?

Your answer would be 200^2in. 8*10 = 80. 80*2(because the box has an opposite side)= 160. Then 2*10 = 20. 20*2 (for the same reason)= 40. 160 + 40 = 200.

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
