hope's mom baked a cake for hope's birthday. It is in the shape of a rectangle 10 inches long and 6 inches wide. If she starts at one corner and puts a candle every 2 inches, how many candles will fit around the edge of the cake?

Answer 1

each long side has 6 candles, counting the corners.

with no corners to worry about, each short side only needs 2 more candles.

Total is thus 6+6 + 2+2 = 16

Or, you can consider the entire perimeter as one long line, of length 32. So, it will need 16 candles to decorate it.
