Yes, it's 60m. I agree.

@ALL.
P=4.8kg/cm^2---> (1)
Now we know that 1kg=10N, put in---> (1)
P=48N/cm^2.
W=.8.
Now calculate hight by formula-P=w.h.
And get answer 60 cm.

Yes, they all are right, the answer must be in a meter.

PRESSURE=(UNIT WT.)*(HEIGHT).
4.8 = (0.8)*(1000/100^3)*(H),
H = 6000 cm.
H = 60 m.
4.8 = (0.8)*(1000/100^3)*(H),
H = 6000 cm.
H = 60 m.

H = p/w.
= 48/.8,
= 60.
= 48/.8,
= 60.

Pressure = W * H.
4.8 * 10^3 = sp. grvty * dnsty * H.
4800 = 0.8 * 1* H.
H = 6000cm = 60m.
4.8 * 10^3 = sp. grvty * dnsty * H.
4800 = 0.8 * 1* H.
H = 6000cm = 60m.

Here, it is converted it in newton by multiplying 10.
Another way to do it is, 1st convert 4.8kg/cm2 into kg/m2 by multiplying it with 10000.
Ten again multiply by 10 to get in N/m2, then find out the specific weight.
=> 8 * 1000 * 10 now divide 480000/8000.
You will get 60 as an answer.
