Question

How many wooden cubical blocks of edge 12 cm can be cut from a cuboidal block of dimensions 1.2 m 0.72 m 0.6 m.

Answer 1

12cm=0.12m
for 1.2m it should be cut into 10 times
0.12*10=1.2m
for 0.72m it should be cut into 6 times
0.12*6=0.72m
for 0.6m it should be cut into 5 times
0.12*5=0.60
=0.6

Answer 2

Answer:

300 wooden cubical blocks of edge 12 cm can be cut from a cuboidal block of dimensions $1.2m\times 0.72m\times 0.6m$.

Step-by-step explanation:

Given a cuboidal block of dimensions $1.2 m\times 0.72 m\tmes 0.6 m$. we have to find the no. of cubical blocks of edge 12 cm can be cut from above cuboidal block.

Volume of cuboidal block=lbh= $1.2\times 0.72\tmes 0.6=0.5184m^3$

Volume of cubical block=$a^3=0.12^3=0.001728m^3$

Now, no. of wooden cubical blocks which can be cut from a cuboidal block can be calculated as

$=\frac{Volume\thinspace of\thinspace cuboidal\thinspace block}{Volume\thinspace of\thinspace cubical\thinspace block}$

$=\frac{0.5184}{0.001728}$

=300

Hence, 300 wooden cubical blocks of edge 12 cm can be cut from a cuboidal block of dimensions $1.2m\times 0.72m\times 0.6m$.
