A 25.0g object has the dimensions of 2.0cm,3.0cm and 5.0cm. What is the density of this object?

0.833 g/cm

The formula for density is mass/volume. The first thing you have to do is find the volume by multiplying the dimensions together. 2 x 3 x 5 = 30, which means the volume is 30. If you plug the mass and volume into the formula, the equation will be 25/30. the answer to this is 0.83 repeating, which rounds to about 0.833. If the question says what decimal place to round to, round it to that place and use that as your answer.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
