(a) The volume of a cubical box is [tex]216 \, \text{cm}^3[/tex]. Find the length of each side.

(b) The volume of a cube is [tex]1,728 \, \text{cm}^3[/tex]. Find the length of each side.



Answer :

Sure, let's solve these problems step by step.

### (a) Finding the side length of a cubical box with volume 216 cm³

Given:
- Volume [tex]\( V \)[/tex] of the cube is 216 cm³.

The formula to find the side length [tex]\( s \)[/tex] of a cube given its volume is:

[tex]\[ V = s^3 \][/tex]

We need to solve for [tex]\( s \)[/tex]:

[tex]\[ s = \sqrt[3]{V} \][/tex]

Substitute the given volume:

[tex]\[ s = \sqrt[3]{216} \][/tex]

When you calculate the cube root of 216, you get:

[tex]\[ s \approx 6.0 \, \text{cm} \][/tex]

So, the length of each side of the cubical box is approximately 6.0 cm.

### (b) Finding the side length of a cube with volume 1,728 cm³

Given:
- Volume [tex]\( V \)[/tex] of the cube is 1,728 cm³.

Similarly, use the formula:

[tex]\[ V = s^3 \][/tex]

Solving for [tex]\( s \)[/tex]:

[tex]\[ s = \sqrt[3]{1,728} \][/tex]

Upon calculating the cube root of 1,728, you get:

[tex]\[ s \approx 12.0 \, \text{cm} \][/tex]

So, the length of each side of the cube is approximately 12.0 cm.

Thus, the solutions are:
- For part (a), the side length of the cubical box is approximately 6.0 cm.
- For part (b), the side length of the cube is approximately 12.0 cm.
