Question

Ratio of sides of a two cubes are in the ratio 2:3. Find ratio of thier tsa

Answer 1

Answer:

$\red {Ratio \: of \: TSA } \green { = 4 : 9 }$

Step-by-step explanation:

$Given \:ratio \:of \: sides \: of \: two \: cubes \\= 2 : 3$

$Let \: side \: of \: first \: cube = 2x \\Side \:of \: second \: cube = 3x$

$Now, Ratio \: of \: TSA\\ = 6\times (2x)^{2} : 6\times (3x)^{2}$

$= 4x^{2} : 9x^{2} \\= 4 : 9$

Therefore.,

$\red {Ratio \: of \: TSA } \green { = 4 : 9 }$
