Answer: The height of the cone is

Step-by-step explanation:
<u>Step 1:-</u>
using formula Volume of the cone given base and height of the cone is 
Given Volume of the cone is V = 30 ft^3
Given base of the cone is B = 8 ft^2
<u>Step 2</u>:-

substituting values, we get

cross multiplication, we get

simplification we get

<u>Final answer</u> :- The height of the cone is

51 feet you have to multiple 32 by 8 it will give you 256 and then divide 256 and 5 and you get 51
