B) 0.441 kg
C) 44.1 kg
D) 0.0441 kg

Answer 1

To find the weight of a stack of 21 tiles, multiply the weight of one tile by 21 and then convert grams to kilograms. A stack of 21 tiles would weigh a) 4.41 kilograms.

Step-by-step explanation:

To find the weight of a stack of 21 tiles, we first need to find the weight of one tile. Given that a single tile weighs 210 grams, we can find the weight of 21 tiles by multiplying the weight of one tile by 21.

210 grams * 21 = 4410 grams. To convert grams to kilograms, we divide the weight in grams by 1000.

4410 grams / 1000 = 4.41 kilograms. Therefore, a stack of 21 tiles would weigh 4.41 kilograms.
