A toy company is considering a cube or sphere-shaped container for packaging a new product. The height of the cube would equal t

Darya [45]

Answer:

Packaging with cube will be more efficient.

Step-by-step explanation:

Given:

A cube and a sphere where the diameter of the sphere is equal to the height of the cube.

Let the height of the cube "x"

Radius of the sphere = $(\frac{x}{2})$

Formula to be used:

Surface area of the cube = $6x^2$ and Surface area of the sphere = $4\pi (r)^2$

Volume of the cube = $x^3$ and Volume of the sphere = $\frac{4\pi r^3}{3}$

We have to compare the ratio of SA and Volumes.

Ratio of SA : Ratio of their volumes :

⇒ $\frac{SA\ of\ cube\ (S_1)}{SA\ of\ sphere\ (S_2)}$ ⇒ $\frac{Volume \ of \ cube\ (V_1)}{Volume\ of\ sphere\ (V_2)}$

⇒ $\frac{6x^2}{4\pi (\frac{x}{2})^2}$ ⇒ $\frac{x^3}{\frac{4 \pi r^3}{3} }$

⇒ $\frac{6x^2}{4\pi (\frac{x^2}{4})}$ ⇒ $\frac{x^3}{\frac{4 \pi (\frac{x}{2})^3}{3} }$

⇒ $\frac{6x^2}{\pi x^2}$ ⇒ $\frac{x^3}{\frac{4 \pi (\frac{x^3}{8})}{3} }$

⇒ $\frac{6}{\pi}$ ⇒ $\frac{6}{\pi}$

⇒ approx $2$ ⇒ approx $2$

⇒ $S_1=2S_2$ ⇒ $V_1=2V_2$

Packaging of the toy with the cube will be more efficient as it has more volume comparatively.
