Question

A square boat made from iron has overall dimensions of 2.00 cm x 11.0 cm x 11.0 cm. It has a mass of 213 g. What is its density?

Answer 1

mass / volume

213/2x121=213/242g/cm^3

Answer 2

Answer: The density of boat is
`0.88g/cm^3`

Step-by-step explanation:

To calculate the volume of boat, we use the equation:

`V=lbh`

where,

V = volume of boat

l = length of boat = 2.00 cm

b = breadth of boat = 11.0 cm

h = height of boat = 11.0 cm

Putting values in above equation, we get:

`V=2.00* 11.0* 11.0=242cm^3`

• To calculate density of a substance, we use the equation:

`\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}`

We are given:

Mass of boat = 213 g

Volume of boat =
`242cm^3`

Putting values in above equation, we get:

`\text{Density of boat}=(213g)/(242cm^3)\\\\\text{Density of boat}=0.88g/cm^3`

Hence, the density of boat is
`0.88g/cm^3`
