Answer:
9 years old.
Step-by-step explanation:
Since the ages of all of these students are being represented in relation to the middle student's age then we can create formulas for each student and then apply them to the formula for the sum of their ages and solve for the middle child's age (M) like so... (oldest child's age is represented by variable O and youngest child's age is represented by variable Y)
O = M + 6
Y = M - 3
30 = (M+6) + M + (M-3) ... combine like terms
30 = 3M + 3 ... subtract 3 from both sides
27 = 3M ... divide both sides by 3
9 = M
Now we know that the middle child is 9 years old.

We have to determine the number of cubic centimeters in 5.78 cubic yards.
Since there are 764555 cubic centimeters in 1 cubic yard.
To convert cubic yard to cubic centimeters, we have to multiply the given cubic yards with 764555.
Therefore, 5.78 cubic yards
= 
= 4419127 cubic centimeters
Therefore, there are 4419127 cubic centimeters in 5.78 cubic yards.
