#### Storyboard Text

• MOM, I am trying to find the surface area of my room to know how much paint we need. Do you think you know how to get the surface area?
• If you want to find the surface area of your room you need to do certain steps to find out.
• Sure, the first step in finding your room’s surface area is by knowing the sum of all the surface of your room.
• I don’t really remember the steps, can you remind them to me
• Mom, my room is a simple rectangular prism, so if I’m not wrong I need to measure the length, width and the height only once.
• Correct! Then don’t forget to use the surface area formula minus the part of your carpet.
• Just to make sure, the formula is 2lh+2lw+2wh but you want me to take out the carpet area 2lh+1lw+2wh?
• Yes, this will give you the surface area that needs to be painted with the ceiling to find what we need to purchase.
• 2(12in x14in)+1(12in x10in)+2(10in x14in) will be 336 + 120 + 280 for a total of 736 in square. Now, I know the amount of surface area that I need to cover with paint.
