A box has a volume of 55cm3 and a density of 5g/cm3. What is the mass of the box?

Step-by-step explanation:

Volume (V) = 55 cm³

Density (d) = 5 g/cm³

Mass (m) = ?

We know density is defined as mass per unit volume so

d = m/v

5 = m/55

m = 55 * 5

m = 275 gram

The mass of the box is 275 gram.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
