To write a number in scientific notation put the decimal after the first digit and drop the zeros and to find the exponent count the number of places from the decimal to the end of the number to express 3,500 use 3.5 x 10 ^ 3 or 3.5E03
Well, since there is no image I am unable to say the exact volume. But here is the volume formula-
V=L times W times H
*V=volume W=width H=height
and you don't actually have to write times you can do the symbol.
Example- if I had a rectangular prism of the width being 5 cubes, the length 8 cubes, and the height 7 cubes(following how many gallons are in a cube 7.5) I would the use my formula. V=LWH- 8 times 7= 56 56 times 5=280 280 times 7.5= 2100
V=2100 (that is your answer reply If you didn't mean the volume or you don't get it)
Is there a picture to show it?
