Question

PLS SOLVE ITS FAST OK​

Answer 1

Answer: 1.96

Explanation:

volume = lbh

v = 2 x 0.5 x 0.25

v = 0.25m³

density = mass/volume

mass = density x volume

mass = 7.8 x 0.25

mass = 1.96

Answer 2

Answer:

First calculate volume = 2*0.5*0.25=0.25 m^3

250000cm^3

Now, mass= volume* density

= 250000*7.8

= 1950000 g= 1950kg.

hope it help
