Question

Six wooden cubical boxes each having 21 cm length are joining end to end. Find the TSA and the volume of the newly formed cube.​

Answer 1

Answer:

TSA is 756$cm^{2}$ and volume is 2000376$cm^{3}$

Step-by-step explanation:

TSA :

now we get to know the new edge or the new l which is $6\times21 = 126$cm

so tsa = $6l^{2}$

Therefore $6\times126$ = 756$cm^{2}$

Volume :

new edge is 126cm

volume = $l^{3}$

therefore $126^{3}$ = 2000376 $cm^{3}$
