6x,5y and 3 those are terms
since 10 students is the most amount of kids on each bus, you can fit less than 10 people on it. so i don't know if the question wants each bus to have to same amount of students or each bus having different amounts.
1 foot = 12 inches
(1 foot)³ = (12 inches)³
12³ = 1,728 in³
To change 10 cubic feet into cubic inches
10 ft³ * 1728 in³/ft³ = 17,280 in³ Choice C. Multiply by 1,728
309 times 692 ***********************
