Question

1. aras has created a hollow cube using her 3d printer. the sides of the cube are each 2 inches long. which is the correct substitution to find the volume of the cube?

a. $p = 4(2)$
b. $v=(2)^{3}$
c. $a=(2)^{2}$
d. $v=\frac{4}{3}(3.14)(2)^{3}$

Explanation:

Step1: Recall volume formula for cube

The volume formula for a cube is $V = s^3$, where $s$ is the side - length of the cube.

Step2: Identify side - length value

The side - length $s = 2$ inches.

Step3: Substitute value into formula

Substituting $s = 2$ into the volume formula gives $V=(2)^3$.

Answer:

B. $V=(2)^3$
