Step-by-step explanation:
The volume for a pyramid is
, where B is the area of the base and h is the height. We are given the volume, and the base and height in terms of x. Our formula then looks like this:
. Simplifying the right side we have
. Multiply both sides by 18 to get rid of the fraction and we have
, so x = 117.575
The least common multiple means that the least multiple that the numbers have in common. So you can make a little chart with each of the numbers multiples like so..
3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69,
(Just added 3 each time)
5,10,15,20,25,30,35,40,45,50,55,60,65,70,
(Just added 5 each time)
7,14,21,28,35,42,49,56,63,70,77
(Just added 7 each time)
No we can go and look through the multiples and see what number they all have that's the same! You might have to keep added on multiples until you find some that are alike! You'll eventually reach 105 for each of the numbers and see that that's the first one that they have that's the same!! So 105 would be your least common multiple!
