Question

find the TSA and LSA of cube with side length 6•5cm please do whole problem​

Answer 1

Given :

• Side of Cube is 6.5cm.

To Find :

• Lateral / Curved Surface Area of Cube.
• Total Surface Area of Cube.

Solution :

For Curved Surface Area :

$\longmapsto\tt{Side=6.5\:cm}$

Using Formula :

$\longmapsto\tt\boxed{C.S.A\:of\:Cube=4{a}^{2}}$

Putting Values :

$\longmapsto\tt{4{(6.5)}^{2}}$

$\longmapsto\tt{4(42.25)}$

$\longmapsto\tt\bf{169{cm}^{2}}$

So , The C.S.A of Cube is 169 cm².

Now ,

For Total Surface Area :

Using Formula :

$\longmapsto\tt\boxed{T.S.A\:of\:Cube=6{a}^{2}}$

Putting Values :

$\longmapsto\tt{6{(6.5)}^{2}}$

$\longmapsto\tt{6(42.25)}$

$\longmapsto\tt\bf{253.5{cm}^{2}}$

So , T.S.A of Cube is 253.5 cm²..

_______________________

• C.S.A of Cube = 4a²
• T.S.A of Cube = 6a²
• Volume of Cube = a³
• Surface Area of Cuboid = 2(lb+bh+hl)
• Volume of Cuboid = l×b×h

Here :

• a = side of cube.
• l = length
• b = breadth
• h = height

$\rm\boxed\checkmark$ $\textsf{\textbf{\blue{Given :-}}}$

• Side of Cube :- 6.5cm

$\rm\boxed\checkmark$ $\textsf{\textbf{\blue{To Find :-}}}$

• T. S. A. and C. S. A. of cube

$\rm\boxed\checkmark$ $\textsf{\textbf{\blue{Solution :-}}}$

• Curved Surface Area :-

$\implies\sf{C. S. A. of cube = 4a²}$

Values :-

$\implies\sf{4(6.5)²}$

$\implies\sf{4(42.25)}$

$\implies\bf{169cm²}$

• C. S. A. of cube = 169cm².

Now,

• Total Surface Area :-

$\implies\sf{T. S. A. of cube = 6a²}$

Values :-

$\implies\sf{6(6.5)²}$

$\implies\sf{6(42.25)}$

$\implies\bf{253.5cm²}$

So,

• C. S. A. of cube = 169cm².

• T. S. A. of cube = 253.5cm².
