Question

the surface are of a cube is[ 18 3/8m^2]
.find it's volume​

Answer 1

Answer:

Step-by-step explanation:

Surface area of the cube = 18 3/4 m^2

=> 6a^2 = 18 3/8

=> 6a^2 = 147/8

=> a^2 = 147/8 x 6

=> a^2 = 147/48

=> a^2 = 49/16 (on solving the fraction)

=> a = root(49/16)

=> a = 7/4 m

Now , volume of cube = a^3

                                    = (7/4)^3 m^3

                                    = 543/64
