Question

Find the surface area of a cube whose volume is 9.251 cube meter

Answer 1

v=9.251
A=6a²
v=a³
A=6V⅔=6·9.25⅔≈26.44095m²

...............hope it helped................

Answer 2

Let the side of the cube be a
Volume of cube = a^3
             9.251.   = a^3
                       a = cube root 9.251
                       a = 2.1 (approx)

Surface area of cube = 6a^2
                                   = 6*(2.1)^2
                                   = 6*2.1*2.1
                                   =12.6*2.1
                                   = 26.46 cm^2
