Question

side of cube is 4.5cm. Find its surface area​

Answer 1

Given :

• Side of Cube is 4.5 cm .

To Find :

• Surface Area of Cube .

Solution :

$\longmapsto\tt{Side=4.5\:cm}$

Using Formula :

$\longmapsto\tt\boxed{Surface\:Area\:of\:Cube=6{a}^{2}}$

Putting Values :

$\longmapsto\tt{6\times{(4.5)}^{2}}$

$\longmapsto\tt{6\times{(20.25)}}$

$\longmapsto\tt\bf{121.5\:{cm}^{2}}$

So , The Surface Area of Cube is 121.5 cm² .

_______________________

• Surface Area of Cube = 6a²
• 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 :

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