Here's a fun

**MATH MEASUREMENT**activity for kids that uses a

**recycled cereal box**.

**Surface Area**is the measurement of the

**OUTSIDE**of a

**solid figure**.

**Materials**- cereal box or other
**rectangular prism**shaped box - scissors
- pencil
- markers (optional)
- ruler

**Directions _- Activity 1**- A cereal box bought at the store is a 3D Shape.We need to turn it into its
(2D representation of a 3D shape).**NET** - Empty everything out of the cereal box.
- Use your scissors to cut the box open. You may need to tape the top and bottom flaps back together because of the design of the box. Your box should look similar to the picture above with 6 areas. (front, back, 2 sides, top and bottom----all flattened out)
- Next you need to use a
**ruler**to find the**AREA**for**each**box**section**. You could do the work and write the area(s) on each section of the box. Remember:**Area = Length x Width** - After you have found the Area for each section, you need to
**ADD**all the 6 different areas together to find the Surface Area! - Voila, you now have the Surface Area of a Cereal Box/ Rectangular Prism in
**square units**!

**Directions - Activity 2**This is an alternative method to find the

**surface area of a rectangular prism**.

You could use the following Formula and a ruler to find the surface area of a rectangular prism

l=length, w=width, h=height |

**Have fun with math!**
How that would have helped me in school. Geez! Why didn't one teacher do that for me lol. I am terrible at Geometry and have been all the way through my MBA (which thankfully was more algebra!).

That was awesome. I always loved math! This would def help my kids if they were older. I showed this to my 3 year old, and he just asked for a bowl of cereal!

Excellent way of describing a figure and its formula.A rectangular prism is one of the solid figures which is actually a cuboid with six surfaces.So,its surface area is just addition of 6 faces.
