Question

Daisy is shipping a package to her daughter, Molly. If the box’s dimensions are equal, and the length is 3 feet long, what is the volume of the box in cubic feet?
A. 1
B. 3
C. 9
D. 27

Answer 1

D, Because 3 cubed is 27. If the box's length is 3 feet then the width and height is also 3.

Answer 2

If "the box's dimensions are equal," and "the length is 3 feet," then 
length=width=height = 3 ft.  The volume is (3 ft)^2 = 27 ft^3.
