Answer:
The total mass of 3 math book = 13.383 kilograms
Step-by-step explanation:
The mass of 1 math book = 4, 461 grams.
So, the mass of 3 math books = 3 x ( mass of 1 math book)
= 3 x 4, 461 grams. = 13, 383 grams.
or, the mass of 3 math book = 13, 383 grams.
Now, 1000 grams = 1 kilogram
or, 1 gram = 1/1000 = 0.001 kilogram
So, 13, 383 grams = 13, 383 x (0.001 kilo grams)
= 13.383 kilograms
⇒ 13, 383 grams = 13.383 kilograms
hence, the mass of 3 math book = 13.383 kilograms
Also, rounding off the answer to the nearest thousandth, we get,
Hence, the total mass of 3 math book = 13.383 kilograms
