Step-by-step explanation:
<u>Standard Form of Numbers</u>
Any number that we can write as a decimal number between 1.0 and 10.0, multiplied by a power of 10, is said to be in Scientific Notation. Some authors consider standard form and scientific form as the same, but others state that standard form is the common form of expressing numbers, i.e., a sequence of digits, separated by thousands by a comma, and separated from the decimal part by a dot.
We'll give here both answers.
We have to calculate:
Since the numbers don't have the same exponent, we must make them equal. Let's make the second number have an exponent of 5, by dividing by 10:
Now we add:
It's correctly expressed in scientific notation. Now to convert to 'standard form', multiply by :
Now.. notice the picture below
it has a front-and-back of 11x4
it has a left-and-right of 6x4
and a top-and-bottom of 6x11
now, if the Surface Area is less than 290in², then is cheaper to manufacture, because it uses less material to make the box
