6
I would round:
1.78 to 2
4.25 to 4
So: 4+2=6
Answer:
573440 kg
Step-by-step explanation:
Given,
Density of copper ( D ) = 8960 kg / m³
Length of cube ( l ) = 4 meters
To find : Mass of solid cube of copper ( m )
Formula : -
Volume of cube = l³
Volume of cube
= l³
= 4³
= 4 x 4 x 4
= 64 meter³
So,
V = 64 meter³
Formula : -
D = m / V
m = D x V
= 8960 x 64
m = 573440 kg
Hence,
The mass of a solid cube of copper is <u>573440</u> kg.
Answer:
30
Step-by-step explanation:
29 - 19 = 10 (difference)
triple 10 now:
10 x 3 = 30
43.3% All you need to do is move the decimal two places to the right and there you go.
