Well, there are different ways to do this if you are really familiar with fractions, but "officially" :P
1) convert mixed numbers to improper fractions.
rule: a b/c = (ac+b)/c
2) make all fractions have a common denominator...
a/b+c/d
(a/b)(d/d)+(c/d)(b/b)
(ad/bd)+(cb/bd)
3)
The simplify your final answer with greatest common denominator or convert back to mixed number if needed...

Step-by-step explanation:
step 1
Find the volume of the square pyramid
The volume is equal to
where
substitute
step 2
Find the volume of one wax block
The volume of a cube is equal to
where
substitute
step 3
Find out the number of wax blocks needed to make the candle
Divide the volume of the square pyramid by the volume of the wax block
so
There is a very great website called Desmos that can efficiently graph any equation. I think it will help a lot :)
Since this function is an absolute value, then it would look like a V shape on a graph. The vertex will always start at (0,0). Inside the absolute value x is subtracted by 3 which means the vertex will move to the right by 3 units. The entire function is added by 6 which means the vertex will move up by 6 units. I've attached a graph showing the final vertex of f(x)=-|x-3|+6 which is (3,6)
Hope This Helps :)
