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 242 g/cm3 0.880 g/cm3 51500 g/cm3 1.14 g/cm3

Answer 1

Volume:

2.00 x 11.0 x 11.0 => 242 cm³

mass : 213 g

D = m / V

D = 213 / 242

D = 0.880 g/cm³

Answer B

hope this helps!

Answer 2

Answer: Density of the boat will be $0.880g/cm^3$

Explanation: Density of a substance is calculated using the formula:

$Density=\frac{Mass}{Volume}$   .....(1)

Here, Dimensions of a boat is given, we can calculate the Volume using:

Volume = length × breadth × height

Dimensions are 2.00cm × 11.00cm × 11.00cm

Volume = 2cm × 11cm × 11cm = $242cm^3$

Mass of the boat = 213 grams

Putting values in equation 1, we get

$Density=\frac{213g}{242cm^3}=0.880g/cm^3$
