Step 1
Given;

Required; How many ounces of water do 9 bottles hold?
Step 2
To do this we will use the ratio;


Answer;
We will calculate this by using ratios and because these two triangles are similar, which is very important.
Explanation:
We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.
9 : 21 = 18 : x
x = (21*18)/9
x = 378/9
x = 42.
The correct answer is B. 42.
Answer:
96 cm³
Step-by-step explanation:
V=1/2×6×8×4=196/2=96cm³
