Analyze problem situations involving measurements concepts, select appropriate strategies, and use an organized approach to solve narrative and increasingly complex problems.
In simpler form: Find strategies to solve simple problems about kinds of measurments that can be used no matter how hard the problem is.

Surface Area of a Cube.

So first lets figure out how to find the area of a square. The formula for that is Base × Height. So if the base of a figure is 2 cm and the height is 3 cm then you would do 3 × 2 which equals 6. That would be there area of that figure.
So as you know a cube has 6 sides which are squares. We already know how to figure out the area of one square. So then you would do the same process but then you would multiply that answer by 6.
If the base of one of the sides on the cube is 3 cm and the height is 2 cm then you would do 3 × 2. The answer would be 6. So then since there is 6 sides you would do 6 × 6 which equals 36 cm. So the surface area of that cube would be 36..

Surface Area of a Cylinder

So first lets find the formula how to find surface area of a cylinder.
Formula = Radius × Radius × 3.14 × Height.
So first of all, radius is half of the diameter for a cylinder. So lets say that we have a cylinder that is 10 cm high and the diameter of it is 6 cm. So we would divide 6 into 2 because radius is half of the diameter. So then your radius would be 3 cm. So then you would do 3 × 3 which equals 9 cm. Then you would take 9 cm and multiply by 3.14. 9 × 3.14 which equals 28.26 cm. So then you would take 28.26 and multiply that by the height which is 10 cm. So 28.26 × 10 = 282.6 cm. So your answer would be 282.6 cm²

You would use this in real life if you were an architect trying to find out how space you would have to find how space you would have to cover.

Here is another formula.
Surface Area of a Cone = pr2 + prs
