Question

The volume of two Cubs are in the ratio 1:27, find the ratio (3) of their total surface area​

Answer 1

Step-by-step explanation:

☘Answer:-

Given:-

• Volume of the cubes is 1:27.

To find:-

• The ratio of the cubes surface areas.

Solution:-

$\frac{a {}^{3} }{b {}^{3} } \: = \: \frac{1}{27}$

$(\frac{a}{b} ) {}^{3} \: = \: ( \frac{1}{3} ) {}^{3}$

$= > \: \frac{a}{b} \: = \: \frac{1}{3} \: \: \: \: \: \: \: \: \: \: \: \: \ \: \: \: \: - - - - (1)$

$Therefore  , \: ratio \: of \: the \: surface \: area$

$\frac{6a {}^{2} }{6b {}^{2} }$

$= \: \frac{a {}^{2} }{b {}^{2} }$

$= \:( \frac{a}{b} ) {}^{2}$

$= \: (\frac{1}{3} ) {}^{2}$

$= \: \frac{1}{9}$
