Question

The function s(V) = Negative RootIndex 3 StartRoot uppercase V EndRoot 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?


s > 0

s greater-than-or-equal-to 4

s greater-than-or-equal-to 8

s greater-than-or-equal-to 16

Answer 1

B. s greater-than-or-equal-to 4

Explanation:

Answer 2

(B)s greater-than-or-equal-to 4

`s\geq 4`

Explanation:

The function
`s(V)=\sqrt[3]{V}` describes the side length, in units, of a cube with a volume of V cubic units.

If Jason wants to build a cube with a minimum of 64 cubic centimeters,

`V\geq 64 $ cubic meters`

Therefore:

`s(V)\geq \sqrt[3]{64}\\s\geq 4 $ Units`

The correct option is B.
