    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
