Question

Volume of a cube is 1.331 cu. cm. Find the surface area of the cube.

Answer 1

Answer:

Volume = 1.331 cm^3

or, a^3 = 1.331

a = cube root of 1.331

 = 1.1 cm

Therefore, edge = 1.1 cm

If the length of edge is doubled ,  

edge = 2*1.1

        = 2.2 cm

Then, volume = 2.2*2.2*2.2 = 10.642 cm^3

Therefore, volume has increased 10.648/1.331 = 8 times.
