@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, it's 60m. I agree.

P=WH, H=P/W, H=48/.8=60.

Sanjay said:   8 years ago
Yes, they all are right, the answer must be in a meter.

BIBEK said:   8 years ago
Answer 60 m is correct. I agree.

PRESSURE=(UNIT WT.)*(HEIGHT).

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

Answer must be 60m. I agree.

Rind said:   9 years ago
H = p/w.
= 48/.8,
= 60.

Sasi said:   9 years ago
Pressure = W * H.
4.8 * 10^3 = sp. grvty * dnsty * H.
4800 = 0.8 * 1* H.
H = 6000cm = 60m.
