Question

The students of a school went on a picnic by bus. The number of students in each of x buses was the same. The number of rows of seats in each bus was 4 more than the number of buses. The number of students who sat on each row of seats was 2 more than the number of rows of seats in each bus. The expression below shows the total number of students in all the buses:

x(x + 4)(x + 6)

How can the total number of rows of seats in all the buses combined be calculated?

By multiplying x and (x + 6)
By multiplying x and (x + 4)
By adding (x + 4) and (x + 6)
By adding (x + 4) and (x + 2)
