Question

How many cubic blocks of wood of side $20cm$ can be cut from a block of wood having dimensions of $2m,80cm$, and $40cm$?

Answer 1

Number of cubic blocks $=\frac{2m\times 80cm\times 40cm}{20cm\times 20cm\times 20cm}$

$=\frac{200cm\times 80cm\times 40cm}{20cm\times 20cm\times 20cm}$

$=10\times 4\times 2$

$=80$
