Dice are often used in various games. The length of one side of a standard die is approximately 1.5 cm and has a mass equal to 3.3
grams.
Assuming the die is a perfect cube, determine it's density.
A)
0.45 g/cm3
0.98 g/cm3
2.2 g/cm3
2.9 g/cm3

Step-by-step explanation:

ρ =  

m

V

=  

3.3 gram

1.5 cubic centimeter

=  2.2 gram/cubic centimeter

10

Step-by-step explanation:

"three times r" = 3r

"three times r minus ten" = 3r - 10

"product of 5 and the difference of three times r minus ten"

= 5 (3r - 10)

given that r = 4,

the expression becomes

5 (3r - 10)

= 5 [3(4) - 10]

= 5 [12 - 10]

= 5 (2)

= 10
