The density of ice is 0.921 g/cm*3, calculate the mass of a cubic block of ice which is 76mm on each side

Answers

Answered by GENIUS1223

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

ramlasya2005: May be the answer is appropriate but not correct

ramlasya2005: the answer is 4.04296x10*2

ramlasya2005: approximation value

ramlasya2005: ok thanks

HEY MATE

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

HOPE IT HELPS ❤️❤️❤️❤️❤️❤️❤️❤️

PLS MARK AS BRAINLIEST✌️✌️✌️✌️✌️✌️✌️

ramlasya2005: Good well tried in simplified way

bluecolor: thankyou
