Question

How many wooden cubical blocks of side 20 cm can be cut from a cuboidal block of wood of size 5 cm multiply 160 cm multiply 80 cm?

Answer 1

Answer:  The answer is 8.

Step-by-step explanation: Given that there is a cuboidal block of wood of size 5 cm × 160 cm × 80 cm. We are to find the number of wooden cubes of side 20 cm that can be cut from the cuboidal block.

Now, area of the wooden cuboidal block is given by

$A=5\times 160 \times 80=64000~\textup{cm}^3.$

And, the area of a wooden cubical block is

$a=20\times 20\times 20=8000~\textup{cm}^3.$

Therefore, the number 'n' of cubical blocks that can be cut from the cuboidal block is

$n=\dfrac{A}{a}=\dfrac{64000}{8000}=8.$

Thus, the answer is 8 cubical blocks.
