Question

Aj has 10,500 grams of sand in his sandbox. He brings home another 2,400 grams of sand from the beach to add to his sandbox. How many kilograms of sand does Aj now have in his sandbox?

Answer 1

AJ originally had 10,500 grams of sand and after adding 2,400 grams from the beach, he now has a total of 12,900 grams. Converting that amount to kilograms results in 12.9 kilograms of sand in his sandbox.

Step-by-step explanation:

AJ initially had 10,500 grams of sand in his sandbox. After adding another 2,400 grams of sand from the beach, the total amount of sand in the sandbox is the sum of these two quantities, which equals 12,900 grams. To convert grams to kilograms, we use the fact that 1 kilogram is equal to 1,000 grams. Therefore, by dividing 12,900 grams by 1,000, we get 12.9 kilograms.

In equation form:

1. Add the amounts of sand: 10,500 g + 2,400 g = 12,900 g.
2. Convert grams to kilograms: 12,900 g ÷ 1,000 = 12.9 kg.

Hence, AJ now has 12.9 kilograms of sand in his sandbox.
