Answer 1

Answer:

I don't no plz tell I can what do

Answer 2

volume=102.4cm3

let height be 5x

then, length=8x

and width=x

Step-by-step explanation:

ATQ:-

volume=l×b×h

102.4=8x × x × 5x

102.4= 40x raise to power 3

102.4=40x × 40x × 40x

102.4 = 12000x

102.4/12000=x

1024/120000=x

32/375=x

so, width=x=32/375

hence, length= 8x= 32/375×8=0.68cm
