Question

A block of wood is in the form of cube whose edge is 3 metre how many rectangular pieces of size 30×20×15cm can be cut from the block

Answer 1

Is this for volume, what grade are you in?

Answer 2

if it is then you would multiply 30x20x15, which is 9000, then I think you divide this by 3. 9000/3= 3000 so the answer would be 3000^3

Answer 3

Since all of 15,20,30 divide 300, the cube is 20x15x10 blocks in size.

So, it can be cut into 3000 blocks.

Or, using the idea above, divide the volume of the cube by the volume of a block:

300^3 / (30x20x15) = 27000000/9000 = 3000
