Question

the total surface area of a cube is 1176 metre square find the length of each side ​

Answer 1

Step-by-step explanation:

Total surface area given =1176m²

Surface area of cube =6a²

6a²=1176

a²=1176÷6

a²=196

a=√196

a=14

So,the length of side of cude=14cm

Answer 2

$\huge\tt\red{SoluTion:-}$

Given that :-

Total surface area of a cube = 1176m²

Find out :-

length of each side

Then according to the question :-

using formula ,

$\huge{\boxed{\pink{ Total\: surface \: area \: of \: cube = 6{a}^{2} } }}$

$\sf\implies$ 1176 = 6a²

$\sf\implies$1176/6 = a²

$\sf\implies$ 196 = a²

$\sf\implies$ √196 = a

$\sf\implies$ 14 = a

Therefore the length of each side is 14m
