Question

how many wooden cubes each of side 15cm. can be cut from a log of wood of dimension 3cm× 30cm× 15cm??

Answer 1

vol of cube =a³
=15³
=3375cm³
vol of log=l*b* h
= 300*30*15. (1m=100cm)
=135000cm³
then the no. of cubes can be but out from the log is=vol of log/vol of cube
=135000/3375
=40
hence 40 cubes can be cut out from the log
