Question

if CSA of a cube is 64cm then find the surface are of cube?​

Answer 1

Answer:

Let a be the side of the cube.

Then given a3=64

or, a=4.

Then its surface area will be 6×a2=6×16=96 cm2.

Answer 2

Step-by-step explanation:

CSA=64cm²

let side be a

LSA/CSA=4a²

64=4a²

64/4=a²

16=a²

√16=a

4cm=a

Side of cube =4cm

Surface area=6a²

=6×4²

=6×16

=96cm²
