Question

find curved / lateral surface area of a
cube witch side 8 am​

Answer 1

Given :

• Length of each side of cube = 8 cm

To find :

• lateral surface area of LATERAL surface area of cube( LSA)

Formula used:

• lateral surface area of cube( LSA)= 4 a²

where a is Length of each side of cube.

Solution :

Length of each side of cube = 8 cm

$\implies \: LSA = 4 {a}^{2}$

now put a = 8

$\implies \: LSA = 4 {(8)}^{2}$

$\implies \: LSA = 4 \times 8 \times 8$

$\implies \: LSA = 4 \times 64$

$\implies \: LSA = 256 \: {cm}^{2}$

Answer :

lateral surface area of the given cube = 256 cm²

Volume of cylinder = πr²h

T.S.A of cylinder = 2πrh + 2πr²

Volume of cone = ⅓ πr²h

C.S.A of cone = πrl

T.S.A of cone = πrl + πr²

Volume of cuboid = l × b × h

C.S.A of cuboid = 2(l + b)h

T.S.A of cuboid = 2(lb + bh + lh)

C.S.A of cube = 4a²

T.S.A of cube = 6a²

Volume of cube = a³

Volume of sphere = (4/3)πr³

Surface area of sphere = 4πr²

Volume of hemisphere = ⅔ πr³

C.S.A of hemisphere = 2πr²

T.S.A of hemisphere = 3πr²
