Approximately how many boxes that are 2 ft. by 2 ft. by 3.5 ft. fit inside of the back of a tractor trailer box truck whose dimensions are 28 ft. by 8 ft. by 9 ft.?
Solution:
Volume of trailer box= Number of boxes * Volume of Box
Volume of Trailer Box=Length*Width*Height
Dimensions of Trailer Box are 28 ft. by 8 ft. by 9 ft.
Volume of Trailer Box=28*8*9ft³=2016ft³
Dimensions of box are 2 ft. by 2 ft. by 3.5 ft.
Volume of Box=2*2*3.5ft³=14ft³
Volume of Trailer Box=Number of Boxes *Volume of Box
2016=Number of Boxes*14
To get, Number of Boxes, Let us divide by 14
2016/14=Number of Boxes=144
Number of Boxes=144
Answer: Option C:144 boxes
