Question

surface area of a cube is 2568 sq. m. Calculate its side​

Answer 1

Answer:

We know that

T.S.A or Total Surface Area of a cube= 6a²

where a= side

here Total Surface Area is 2568

that is

6a²=2568

a²=2568÷6

a²=428

a=√428

a=√(107×2×2)

a=2√107

therefore each side of the cube= 2√107m

Let's Check whether it's correct or not

6×(2√107)²=2568

6×(4×107)=2568

6×428=2568

2568=2568

L.H.S=R.H.S

hence verified
