Question

Find total surface area of a cube whose each sind in 6 CM.

Answer 1

Given :

• Side of Cube is 6 cm .

To Find :

• Total Surface Area of Cube .

Solution :

$\longmapsto\tt{Side=6\:cm}$

Using Formula :

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

Putting Values :

$\longmapsto\tt{4{(6)}^{2}}$

$\longmapsto\tt{4(36)}$

$\longmapsto\tt\bf{144\:{cm}^{2}}$

So , Total Surface Area of Cube is 144 cm² ...

_______________________

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

Here :

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