Question

2 A rectangular piece of wood measures 4 cm by 6 cm by 8 cm and has a mass of 20 g. What is the
density of the piece of wood? Will this piece float in water or not?
​

Answer 1

Answer:

density=mass/volume

Explanation:

density of wood=20/1000

density of wood=00.2

Answer 2

Answer:

1. Question

Mass=10g.

volume of solid piece=volume of water level raised

Volume=5ml or 5 cm³

Hence density of solid block is :

Density=mass/volume

=10g/5cm³

=2g/cm³

hope this helps you

as i hace told you earlier it will be 2

1. Question

we know that,density =mass/volume

mass =20 g. (given)

volume=length×breadth×height

so, volume=4cm×6cm×7cm

= 192cm³

therefore, density=mass/volume

=20/192

=0.1041666

since it's is less than water's density [as waters density is 1g/cm³

As a result it will flow on water

hope this helps you

Explanation :

as my mom told me to read i went

so i didn't answered you

and the person who has given the answer

he game the wrong answer

so i was misguided

sorry miss tomboy marvel
