Dylan has two cubes of iron. The larger cube has twice the mass of the smaller cube. He measures the smaller cube. It's mass is
20 grams, and its density is 7.87 g/cm3. What's the larger cube's volume?
1 answer:
Density

is given by

where m is the mass of the object
V is the Volume of the object
let m1 be the mass of the smaller cube
let m2 be the mass of the larger cube
you know that the larger cube has twice the mass of the smaller cube
or m2=2*m1
so apply this information into the density equation and you can determine the volume of the larger cube

Thx have a great day :)
Step-by-step explanation:
The answer would be -8.4.
Step-by-step explanation:
1. add the numbers all together
(of the pets)
= 40 pets total
40 pets =100%
1 pet = 2.5%
percents:
Cat= 10, or 25%
Dog = 15, or 37.5 %
fish=8 or 20%
bird= 7 or 17.5%
angles:
dog= 135
cat= 90
fish= 72
bird= 63
