Question

4) The volume of a cube is 1000 cubic cm. Find its total surface area.​

Answer 1

Step-by-step explanation:

Volume of a cube = side

3

=1000cm

3

=> side =

3

1000

=10 cm

Total surface area of a cube of edge a =6a

2

So, the total surface area of the cube of edge a =10 cm =6(10)

2

=600cm

Answer 2

Step-by-step explanation:

the edge of the cube is ‘a’ then volume of the cube = a3 

Given: Volume of cube = 1000 cm3 

⇒ a3 = 1000 

⇒ a =10 cm 

∴ Edge of the cube  = 10 cm 

Surface area of the cube = 6a2 =  

6 x 10 x 10 = 600 cm2.
