What is the length of the side of a cube whose volume is $275\ cm^3$? Make use of the table for the cube root.
Given:
Volume of a cube is $275\ cm^3$.
To find:
We have to find the length of the side of the cube.
Solution:
Volume of the cube $=275 \mathrm{~cm}^{3}$
This implies,
Length of the side $=\sqrt[3]{\text { Volume }}$
$=\sqrt[3]{275}$
$=\sqrt[3]{27.5 \times 10}$
$\sqrt[3]{27.5}$ lies between $\sqrt[3]{27}$ and $\sqrt[3]{28}$
$\sqrt[3]{27}=3.000$
$\sqrt[3]{28}=3.037$
For the difference $(28-27)=1$,
The difference in the values $=3.037-3.000$
$=0.037$
This implies,
For the difference of $0.5$,
The difference in the values $=0.037 \times 0.5$
$=0.0185$
Therefore,
$\sqrt[3]{27.5}=3.000+0.0185$
$=3.0185$
$\sqrt[3]{10}=2.154$
Therefore,
$\sqrt[3]{275}=\sqrt[3]{27.5} \times \sqrt[3]{10}$
$=3.0185 \times 2.154$
$=6.5018$
$=6.502 \mathrm{~cm}$
The length of the side of the cube is $6.502\ cm$.
