Answer 1

Answer:

• it can be solved by two method

Step-by-step explanation:

$I^{st}$

answer = d = m/v

given d =0.921g/cm

s=76mm=7.6cm  

v=7.6^3=438.976

thus mass = d * v

=0.921*438.976

=404.296896  g

$II^{nd}  method$

Volume = (side length)3 = (76)3 = 438976 mm3 = 438.976 cm3

​Density = mass/volume  

So mass = density×volume = 0.921 g cm-3 × 438.976 cm3  

               = 404.2968 g
