Question

Monica has 4 boxes to place in an empty carton the mass of each box is 4.5 kilograms the mass of the carton is 500 grams what is the total mass in grams of the carton and the 4 boxes?

Answer 1

18.5 kilograms

Explanation:

so first we can convert the values to have a common unit

so 4.5kg is also equal to 4500 grams

next we can find the mass of the 4 boxes

this can be modeled with the expression:

4*4500 which equals 18000

now we have to add the mass of the carton which is 500 grams

18000+500=18500

or 18.5 kilograms

Answer 2

Total mass in grams of the carton and the 4 boxes is 18.5 kg .

Explanation:

Here we have , Monica has 4 boxes to place in an empty carton the mass of each box is 4.5 kilograms the mass of the carton is 500 grams.

We need to find the total mass in grams of the carton and the 4 boxes . Let's find out:

Total mass = Mass of 4 boxes + Mass of empty carton

Mass of 1 box = 4.5 kg

Mass of 4 boxes =
`4.5(4) = 18kg`

Mass of 4 boxes =
`18kg`

Mass of empty carton =
`500g` = 0.5 kg

⇒ Total mass = Mass of 4 boxes + Mass of empty carton

⇒ Total mass =
`18 + 0.5`

⇒ Total mass =
`18.5\ kg`

Therefore, total mass in grams of the carton and the 4 boxes is 18.5 kg.
