8 metres, as it is 800 centimetres.
1cm = 10 mm 80 cm =80*10 =800 cm Hence 80 cm is equal to 800 mm
There is no greater length because while centimeters is a measure of length, grams are a unit of weight, so there is no available comparison.
Any area you want greater than 0 cm2 and less than or equal to 16 cm2. perimeter_of_rectangle = 2 x (width + length) 16 cm = 2 x (width + length) ⇒ width + length = 8 cm ⇒ length = 8 cm - width Neither dimension can be negative, so they are both greater than 0 cm and less than 8 cm. Area_of_rectangle = width x length ⇒ area = width x (8 cm - width) = 8 x width - width2 cm2 This has a minimum value when width = 0 cm or 8cm of 0 cm2, so the area of the perimeter must be greater than 0 cm2 (as the width can be neither 0 cm nor 8 cm). This has a maximum value when width = 4 cm: max_area = 8 x 4 - 42 cm2 = 16 cm2. when the width is between 0 cm and 4 cm (and so the length is between 8 cm and 4 cm) the area is between 0 cm2 and 16 cm2 When the width = 4 cm, the length is also 4 cm, that is the rectangle is a square.

A cube with a side length of 8 cm has a volume of 512 cubic cm.
The length is 14 cm
perimeter = 2*width + 2*length 36= 2*8 +2*length2*length=36-162*length=20length = 10 cm
Take the circumference (8 cm) times turns of wire (8) equals 64 cm
A rectangular prism that has a length of 7 cm, width of 8 cm and height of 14 cm has a volume of 784cm3
Example:- What are the dimensions of a rectangle when its length is greater than its width by 4 cm and has an area of 96 square cm? Let the length be x+4 and the width x: length*width = area (x+4)*x = 96 => x2+4x-96 = 0 => (x+12)(x-8) = 0 when factored So: x = -12 or x = 8 the dimensions can't be negative Solution: length = 12 cm and width = 8 cm Check: 12*8 = 96 square cm
length = 36/4.5 = 8 cm
