Question

You have a stack of sticky notes in six different colors. There are 600 sticky notes in the stack(100 of each color). The height is 6 cm, and the width and length are both 7.62 cm. The six colors are stacked on top of each other with the height(so each colored stack is 1cm).

1. What is the volume of each section? Describe two methods to find the volume of one of the sections.

2. What is the height of one sticky note? Describe two methods to find the height of one sticky note.

3. A stack of circular sticky notes has 400 sticky notes in total. The cylinder has a diameter of 3 in. and a height of 0.8 in. Find the surface area of one sticky note. Use 3.14 for pi. Show your steps.

Thank you so much for helping!!

Answer 1

Answer:

1. 58.0644

2. 0.01

3. 14.16

Step-by-step explanation:

1. V = l*w*h

   v = 7.62*7.62*1

   v = 58.0644

              or

    v = 7.62*7.62*6

    v = 348.3864

    v = 348.3864/6

     v =  58.0644

   

2. 1cm/ 100 sticky notes = 0.01

    6cm/ 600 sticky notes = 0.01

3. A=2πrh+2πr2

      =2·π·1.5·2×0.002+2·π·1.52

      =14.15602
