volume of cube = 44×44×44 (1)
volume of bullet = 4/3 ×pi r^3
= 4/3× 22/7×8 (2)
ans=(1)/(2) = 2541

The Length Of The Edge Of The Cube x = 44cm
Volume Of The Cube = x³ = 44³= 85184cm³
The Radius Of the Spherical bullet r = 2cm
Volume Of 1 bullet = 4/3 pie r³
= (4 / 3) * 22/7 * 2³
= 32 * 22 / 21
Let no. of bullets be n
n = 85184 * 21
----------------
32 * 22
n = 2541 bullets
Thus 2541 bullets can be made hope it helps you
