Help me to answer this pls​
zepelin [54]

The 6 angles with vertex P are:

  1. Angle APB
  2. Angle APC
  3. Angle APD
  4. Angle BPC
  5. Angle BPD
  6. Angle CPD

The letter P must be in the middle since this location is the vertex. Something like angle BPA is the same as angle APB. We can swap the order of the outer letters without any change to the angle itself. Effectively, this means each angle has two possible names.

Calculate the cost of manufacturing a standard cereal box if cardboard costs $0.05 per square inch.
leonid [27]
The volume of the box in this problem doesn't really matter, considering that a cereal box is hollow. Assuming the surface area is 174 inches², then you can simply multiply 0.05 x 174, which is 8.7. Then put that number in the form of money to get $8.70. (seems a bit pricey for one cereal box to me ;P)
