Answer 2

~Anzwer :-

If the weight of one box is $ \rm{3\frac{1}{2}}$. Weight of three box;

• Simplifying the weight of one box :-

$3 \frac{1}{2} = \frac{3 \times 2 + 1}{2} = \frac{7}{2}$

$\rm{ = \frac{7}{2} \approx3.5 \: kg}$

• Finding weight of three such boxes :-

$3.5 \times 3$

$\rm{ = 10.5 \:kg }$

∴ Hence, weight of three such boxes will be 10.5 kg.
