Question

the surface area of a cube is 98/3 cubic metre. find the volume of the cube

Answer 1

Hi Priyanshu37 !
______________________________________________________________
Surface area of Cube = 98/3 m²
Surface area of cube  = 6l²(if the side of cube is l)
ATQ
 6l²  =98/3
18l² =98
    l² =98/18
    l² = 5.44 
  √ l²=√5.44
     l = 2.33 m 
____________________________________________________________
So volume of cube = l³
                               = (2.33)³
                               =12.68 m³

Answer 2

let the side of the cube be "a"

surface area = 6a²
6a² = 98/3

a² = 98/3/6
a² = 5.45
a= √5.45
a= 2.34

volume = a³
=(2.34)³
=12.68


hope it helps!!!!
