Answer 1

this can be obtained by dividing volume of block by volume of a bullet... got it... (ignore my grammatical mistake because I have ignored that in your question also) hope it helps plzz... comment on it, follow me if you wish or mark it brainlest if you want free 3 points....

Answer 2

Volume of block = 11 dm x 1 m x 5 m
= 110 cm x 100 cm x 50 cm= 550000 cm
 Volume of bullet = (4/3) x p x r3 = (4/3) x 3.14 x (2.5)3= 65.4 cm3 (approx).
Number of bullets = 550000/65.4 = 8410 (nearly)
