What kind of tree does a math teacher climb? 2. What do you have to know to get top grades in geometry? 3. What do your eyes do when you see a tough geometry problem? 4. Which triangles are the coldest? 5. What's the best dessert in the Math Teacher's Café? 2. Presentation A square gift box with a height of 5 cm. If you were to fill the box with confetti, what is the maximum amount of confetti (in cubic centimeter) you could use? How can we get the amount of confetti that can be filled in the box? Very Good!! We must get the volume of the cube by means of using the formula V=s3, where V is volume and s is the side of a cube. Again, what is the measure of the cube? Correct! Since you are given 5 centimeter as the side of a cube, multiply 5 by itself three times. What is the volume of the cube? That’s right! Using the formula in getting the volume of a cube V= s3, we will come up with an answer of 125.
