Question

A block of wood has a mass of 180 grams it is 10.0cm long, 6.0cm wide and 4.0cm thick what is it’s volume and density

Answer 1

Density = 0.75 g/cm³

Step-by-step explanation:

Density of a substance is given by

`Density(\rho) = (mass)/(volume)`

From the question

mass of the wood = 180 g

Since the wood is a cuboid we can find the volume using the formula

Volume = length × width × height

From the question

length = 10cm

width = 6 cm

height = 4 cm

Volume = 10 × 6 × 4 = 240 cm³

Substitute the values into the above formula and solve for the Density

That's

`Density(\rho) = (180)/(240) \\ = (3)/(4)`

We have the final answer as

Density = 0.75 g/cm³

Hope this helps you
