Question

answer please....................

Answer 1

side of cube equal to 4 cm
volume equal to 64 cm cube


diagonal of cube equal to diameter of a sphere
$\sqrt{3} \times 4 = diameter \: of \: sphere$
$\sqrt{3} \times 2 = radius \: of \: sphere$
volume of a sphere equal to
$4 \: by \: 3 \: \pi \: r {}^{3}$
$4 \: by \: 3 \: \times 22 \: by \: 7 \times 2 \sqrt{3} \times 2 \sqrt{3} \times 2 \sqrt{3}$
$(4 \times 22 \times 2 \times 2 \times 2 \sqrt{3} ) \: by \: 7$
$704 \sqrt{3} \: by \: 7$
volume sphere - volume of cube
equal to the gap between sphere and walls of cube.
