I would stand on the shoulders of giants, boldly go where others have gone
before, and take advantage of the information that's already available to me.
Since I already know that it's a 5cm box, and ' 5 ' is a rather convenient number,
I would stick with a winner and adopt the 'centimeter' as my unit of measurement.
The area was approx 19.6 square units.
4 x 5cm = 20cm
The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.
5cm*5cm*5cm = 125 cubic cm.
The volume of a cube of 5cm is: 125 cm3
The perimeter is the total distance around a two-dimensional shape. To find the perimeter of a shape, you need to add up all the lengths of its sides. In this case, the perimeter of a shape with sides measuring 5cm and 2cm would be 5cm + 5cm + 2cm + 2cm = 14cm.
5cm to the 3rd power = 5cm x 5cm x 5cm = 125cm3 (or 125 cubic centimeters)
9cm + 5cm + 9cm + 5cm = 28cm
125 cm3
5cm, 5cm, and 5cm could represent the lengths of the sides of an equilateral triangle, or might indicate the length, width, and height of a cube.
8x5x7=280 add the units so answer is 280cm
In international units of measure, it is exactly 5 square centimeters.
