Question 33

If a cube fits exactly in a cylinder with height h, then the volume of the cube is ___ and surface area of the cube is ___.

Answer 1

$h^3,6h^2$
Since, the cube fits exactly in the cylinder with height h, therefore each side of the cube = h
Now, volume of the cube $=(Side{)}^3=h^3$
and surface area of the cube $=6\times (Side{)}^2$
$=6\times h^2$
