Question

Sarah packed 12 boxes of sweets each weighing 625 grams. What is the total weight of the boxes of sweets Sarah packed?

• A. 7 kilograms
• B. 7.5 kilograms
• C. 8 kilograms
• D. 8.5 kilograms

Answer 1

The correct option is B

7.5 kilograms

Weight of one box of sweets = 625 g
Number of boxes = 12

$\therefore$ Total weight of the sweets
= 625 $\times$ 12 g = 7500 g

Since 1000 g = 1 kg, we have
$\therefore 1\text{g}=\frac{1}{1000}\text{kg}\therefore 1\text{g}=0.001\text{kg}\Rightarrow 7500\text{grams}=7500\times 0.001\text{kg}=7.5\text{kg}$

Thus, the total weight of the boxes of sweets Sarah packed is 7.5 kilograms.
