A chocolate bar measures 50 mm wide, 90 mm long, and mm high. Will’s Wrapping Company is making a wrapper to cover the chocolate bar. Use the correct net and determine how much paper will be needed to make the wrapper.

Add up all of the little areas:

100 x 90

3.5 x 50 x 2

3.5 x 90 x 2            add all of those together to get the total area.....cheeky

 

(I assumed the left 50 mm measurement does NOT include the 3 1/2 mm dotted rectangle)
