    "Geometry," meaning "measuring the earth," is the branch of math that has to do with spatial relationships. In other words, geometry is a type of math used to measure things that are impossible to measure with devices. For example, no one has been able take a tape measure around the earth, yet we are pretty confident that the circumference of the planet at the equator is 40,075.036 kilometres (24,901.473 miles) . How do we know that? The first known case of calculating the distance around the earth was done by Eratosthenes around 240 BCE. What tools do you think current scientists might use to measure the size of planets? The answer is geometry.…

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.…
