The volume of a cube is 1000 cm^3 . Find its total surface area .

Answers (1)

Solution :  Let the length of each edge of the cube be $a$  $cm$  . Then ,

Volume of each cube = $\left ( edge \right )^3=(3^3)m^3=27m^3$

Volume of the cuboid $=$ $(18\times12 \times 9)m^3= 1944m^3$

$\therefore$             Number of cubes $=$  volume of the cuboid / volume of each cube $=$  $\frac{1944}{27}=72$
