1. find volume V=LWH V=25*13*14 V=4550 each covers 1000 how many will cover the whole thing? we can't put 4 becuase that leaves 550 uncovered add another
5 is answer (it is too much , but at leas not too little) answer is D
2. V=LWH V=6*4*10 V=240
answer is D
3. count how many are there, don't forget the hidden ones 13 cubes volume=legnth tiems width times height cubes so v=side^3 side=3 3^3=27 13 cubes 13*27=351 in^3
challenge (this is meant to challenge you, not for you to ask people, but I will solve anyway, robbin you of experience)
V=LWH V=5880 H=30 5880=LW30 divide both sides by 30 196=LW they have square bases so L=W 196=L^2 sqrt both sides 14=L=W the side legnth is 14in
