Question 1021647
The volume of the ice block is 8*5*3=120 cu in.

for cone, V=1/3base*height and base is pi r^2

120=1/3 h * pi * 4^2

120 = 16/3  h * pi

120 * 3/16 = pi * h

22.5 = pi * h

h = 22.5 /3.1416

h= 7.16 in. 

Note - this answer is correct for Math class, but not science class. When ice melts, it reduces in volume, about 9%. So a science teacher would expect you to take the 120 cu in and multiply by .91 before continuing. 

I believe the other posted answer is not correct. 

Vol of cone is 1/3 BH

The base is 16pi and my height is 7.16

(16*3.1416*7.16)/3 = 119.97 not 120 due to rounding.
