Question

One box of chocolates weighs $471.5g.$ Find the weight of half a dozen such boxes in $kg$.

Answer 1

Step 1. Calculating weight of half a dozen boxes.

As we know,

$\begin{array}{rcl}1dozen& =& 12units\\ halfadozen& =& \frac{1}{2}\times 12=6units\end{array}$

Given weight of one box is $471.5g.$

So, Weight of half a dozen such boxes will be $471.5g\times 6=2829g$

Step 2. Convert the unit in $kg$.

As we know $1g=\frac{1}{1000}kg$

So, $\begin{array}{rcl}2829g& =& 2829\times \frac{1}{1000}kg\\ & =& 2.829kg\end{array}$

Hence, the result is $2.829kg$.
