A Radically Imaginary
نص القصة المصورة
- Clara, Grade 9 student in Valley Stone Academy
- Hmmm.. I need to get something for Matthew. It's his birthday tomorrow. Hmm.. What does he want, but doesn't have?
- Oh, wait! He has been wanting a rubik's cube for a long time! I should get him that.
- However. I only have 5 square yards of wrapping paper.
- I should get help. Luckily. I know a person.
- Yeah. So my problem is:I wanted to buy a rubik's cube for Matthew's birthday. However. I only have 5 square yard of wrapping paper. I need to find a cube that I can fit inside that wrapping paper.
- So, you call because of a math problem?
- Elena, Clara's classmate and friend
- So, that question is a Radical Expression. We learned that in class last week. But, I'll help you. So the formula for th-
- Clara:WAIT, WAIT, WAIT, DON'T TELL ME HOW TO SOLVE IT!
- Just trying to understand it is hard for me. I need you to show, not tell! Like, write them on a board!
- Elena:Hmmm.. I don't feel like writing. I need you to think for me. Now, close your eyes and picture the formula and the solving process.
- Elena:Okay. Now, picture this..
- So. You wanted to buy a rubik's cube. But you only have a 5 square yards of wrapping paper..
- RUBKI'S CUBE
- FIVE SQUARE YARDS OF WRAPPING PAPER
- So the formula for the cube with the longest edge length [S] you can buy is s equal square root of A over 6, where s is the edge length, and A is the surface area.
- S
- A 6
- So the 5 yard is the surface area. So you place the 5 where the A is. So now you get s equal square root of 5 over 6.
- S
- 5 6
- Now, onto the solving. You first divide. So 5 divide by 6 is equal to 0.8333 and so on. That's a repeating number.
- S
- 0.8333
- Lastly. You square root the quotient. the square root of 0.8333 is 0.9128 and so on.
- S
- 0.9128
- Lastly. You square root the quotient. the square root of 0.8333 is 0.9128 and so on.
- 0.9128
