A small rectangular package has an area of 9x square units and a height of 5 units. A large rectangular package has an area of 6 square units more and a height of 3x units more than the small box.
Which of the following equations could be used to determine the volume of the large rectangular box?
OA.
y = (27:2 + 63.1 + 30) cubic units
OB. y = (27:2 + 30 cubic units
OC. y = (1512 + 8) cubic units
OD. y = (1212 +235 + 11) cubic units
