Answer 1

Hey user

Here is your answer :-

______________________________

We know that

$density = \frac{mass}{volume}$

In first case

mass = 350 kg

volume = 175 m^2

Density = 350 / 175

= 2 kg/m^2

In second case

mass = ?

Volume = 190 m^2

density = 4 kg/m^2

4 = mass/ 190

mass = 4 × 190

= 760

Mass = 760 kg

Answer 2

Density= mass/volume
(i)density =350/175
density = 2kgm^-2
(ii)mass = density ×volume
mass = 190×4
mass= 760kg
hence your answer is correct
