Question

The dimensions of a cuboid ice-cube are $50$ cm $\times 30$ cm $\times 20$ cm. Find its weight in kg. If weight of $1000$$c{m}^3$ is $900$ gm.

• A. $270kg$
• B. $27kg$
• C. $2.7kg$
• D. $0.27kg$

Answer 1

The correct option is B $27kg$

Volume of cuboid of ice $=50\times 30\times 20$

$=30,000c{m}^3$

Weight of $1000c{m}^3=900gm$

Weight of $30,000c{m}^3=30\times 900gm$

$=27000gm$

$=27kg$
