Question

The function s(V) = describes the side length, in units, of a cube with a volume of V cubic units. Jason wants to build a cube with a minimum of 64 cubic centimeters.

What is a reasonable range for s, the side length, in centimeters, of Jason’s cube?

Answer 1

B

greater or equal to 4

Answer 2

The function for the volume of the cube is
s(V) = V³

The minimum volume of the cube is
s(V) ≥ 64 cm³
V³ ≥ 64
V ≥ ∛64
V ≥ 4

The range of the value is from 4 to positive infinity.
