Question

The number of soaps of size $10cms\times 5cms\times 2.5cms$ that can be put in a box of a cuboid of size of $20cm\times 10cm\times 10cm$ is

• A. $20$
• B. $16$
• C. $10$
• D. $5$

Answer 1

Answer: (B)

$16$

Given the measurement of the soap is $10\times 5\times 2.5$.

So the volume of the soap is $125$ cm${}^3$.

Also given the measurement of the cuboid box is $20\times 10\times 10$.

So the volume of the box $=2,000$ cm${}^3$.

Now number of soap can be put in the box is $=\frac{2000}{125}=16$.
