Question

Dimensions of cuboidal ice is $50cm\times 30cm\times 20cm$. Find its weight in kilogram. If weight of $1000c{m}^3$ ice is $900$ gram.

Answer 1

Volume of cube $=$length $\times$ breadth $\times$ height

$=50\times 30\times 20=30000c{m}^3$

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

$\Rightarrow$ Weight of $30000c{m}^3=\frac{900}{1000}\times 30000=27000$ grams

$=27$ kg.
