I'm a student and i have 3 questions to ask you.
1. If 3lugs is equal to 5 mugs
    If 1mug is equal to 7tugs
    If 6tugs is equal to 3pugs
    If 10pugs is equal to 4 bugs. How many Bugs are equal to 48Lugs?

2. A liquid has a D=2.62g/ml. How many mls are needed for 50.0g of liquid?

A cube has a dimensions L=10.6mm W=0.15cm H=1.248*10^-2Km.
The mass of the cube is 13.6g. What is the density of the cube in g/cm3 to the correct number of Sig. Figures?

Show us what you already did.

Okay while for:
2. D= m/v , so there 2.62g/ml= 50.0g/v, so i mulplity v to both sides so now its V*2.62g/ml= 50.0g, then i divided 2.62g/ml from both sides so that leave the equation as V=50.0g/2.62g/ml. And i got that there is 19.08mls needed.

3. i used the same formula D=M/V, but first i changed L= 10.6mm to 1.06cm, W= 0.15cm, and H=1.248*10^-2 Km to 1248*10^-5cm. Then I mulplity L*W*H=0.0198432cm^3. So, then D= 13.6g/0.0198432cm^3. So the Density=685g/cm^3

1. I just don't understand it.
