Can you give me a example of surface area?
Surface area is the perimeter (amount of space around a shape) around a shape. For example: I have a rectangle So: 3+3=6 9+9=18 18+18=36cm2
What is the area with a base of Cm and a height of Cm?
Area is 36cm2
What is the volume of the cube if the base is 36cm2?
216 cubic cm
What is the largest and the smallest perimeter posssible for a rectangle with a area of 36cm2?
The smallest perimeter is that for a square with sides of 6 cm. That is to say, a perimeter of 4*6 = 24 cm. There is no maximum. Suppose the shorter side is x cm. Then, for the area to be 36 cm2, the longer side must be 36/x cm Then the perimeter is 2x + 72/x cm. x can decrease towards 0 and as it does 72/x will increase without limit, making the perimeter "infinite". Try it: If smaller side 1 cm, then longer side = 36 cm and perimeter = 74 cm 0.1 cm 360 cm 720.2 cm 0.01 cm 3600 cm 7200.02 cm etc
What is the area of a rectangle that has a length of 9 cm and a width of 4 cm?
The area of a rectangle is always length multiplied by width. Therefore, the area of the mentioned rectangle is 36cm2.
