Question

The side length of a cube is (x^2-1/2). Determine the volume of the cube.

Answer 1

$\\ \sf\longmapsto volume=side^3$

$\\ \sf\longmapsto volume=(x^2-1/2)^3$

$\\ \sf\longmapsto volume=(x^2)^3-3x^4(1/2)+3x^2(1/2)^2-(1/2)^3$

$\\ \sf\longmapsto Volume=x^6-3x^4/2+3x^2/4-1/8$

Answer 2

Answer:

Step-by-step explanation:

x^6 − (3x^4)/2 + (3x^2)/4 − 1/8

The volume of a cube is Length^3.

If a length is (x^2-1/2, then cube root it

It will then be (x^2-1/2) x (x^2-1/2) x (x^2-1/2).
