Answer:
Given :
Sides of Cube are 3 cm , 5 cm , 7.2 m , 6.8 m and 5.5 m .
To Find :
Total Surface Area of Cube .
Solution :
(i) Side of Cube = 3 cm
Using Formula :
\longmapsto\tt\boxed{T.S.A\:of\:Cube=6\:{a}^{2}}⟼
T.S.AofCube=6a
2
Putting Values :
\longmapsto\tt{6\times{{(3)}^{2}}}⟼6×(3)
2
\longmapsto\tt{6\times{9}}⟼6×9
\longmapsto\tt\bf{54\:{cm}^{2}}⟼54cm

(ii) Side of Cube = 5 cm
Using Formula :
\longmapsto\tt\boxed{T.S.A\:of\:Cube=6\:{a}^{2}}⟼
T.S.AofCube=6a
2
Putting Values :
\longmapsto\tt{6\times{{(5)}^{2}}}⟼6×(5)
2
\longmapsto\tt{6\times{25}}⟼6×25
\longmapsto\tt\bf{150\:{cm}^{2}}⟼150cm

(iii) Side of Cube = 7.2 m
Using Formula :
\longmapsto\tt\boxed{T.S.A\:of\:Cube=6\:{a}^{2}}⟼
T.S.AofCube=6a
2
Putting Values :
\longmapsto\tt{6\times{{(7.2)}^{2}}}⟼6×(7.2)
2
\longmapsto\tt{6\times{51.84}}⟼6×51.84
\longmapsto\tt\bf{311.04\:{m}^{2}}⟼311.04m
2
___________________
(iv) Side of Cube = 6.8 m
Using Formula :
\longmapsto\tt\boxed{T.S.A\:of\:Cube=6\:{a}^{2}}⟼
T.S.AofCube=6a
2
Putting Values :
\longmapsto\tt{6\times{{(6.8)}^{2}}}⟼6×(6.8)
2
\longmapsto\tt{6\times{46.24}}⟼6×46.24
\longmapsto\tt\bf{277.44\:{m}^{2}}⟼277.44m
2
___________________
(v) Side of Cube = 5.5 m
Using Formula :
\longmapsto\tt\boxed{T.S.A\:of\:Cube=6\:{a}^{2}}⟼
T.S.AofCube=6a
2
Putting Values :
\longmapsto\tt{6\times{{(5.5)}^{2}}}⟼6×(5.5)
2
\longmapsto\tt{6\times{30.25}}⟼6×30.25
\longmapsto\tt\bf{181.5\:{m}^{2}}⟼181.5m
2
So , The Total Surface Area of Cube is 54 cm² , 150 cm² , 311.04 m² , 277.44 m² and 181.5 m² respectively .
