`30.45ft^3 = 1/3xx6.3ftxx2.5ftxxh---(1)`

Make h as the subject.

Multiply (1) by `3 ` and then divide it by `(6.3ftxx2.5ft)`

`(30.45ft^3xx3)/(6.3ftxx2.5ft)= h`

`h = 5.8ft`

*So the answer is h = 5.8ft*

`30.45ft^3 = 1/3xx6.3ftxx2.5ftxxh---(1)`

Make h as the subject.

Multiply (1) by `3 ` and then divide it by `(6.3ftxx2.5ft)`

`(30.45ft^3xx3)/(6.3ftxx2.5ft)= h`

`h = 5.8ft`

*So the answer is h = 5.8ft*
