This question is easier to solve by first converting the volume to cubic centimetres (millilitres), because 1 millilitre of water weighs 1 gram and 1 litre weighs 1 kilogram.
1 ft is 30.48 cm.
1 ft * 1 ft * 1 ft
= 30.48 cm * 30.48 cm * 30.48 cm
= 28,316.8466 cm3
Now, we divide that by 1000 to convert that to litres, and knowing that 1 L weighs 1 kg of water, we get the weight.
= 28.317 kg
If you want the answer in lbs, then multiply by the number of lbs in 1 kg.
28.317 kg * 2.205 lbs/kg
= 62.43 lbs
I have a method which I claim is even easier: Look it up and memorize it.
With that method, I have been using 62.4 pounds for many years.
It has worked for me, but I confess that I am only an engineer.

Depends entirely on the material. For example 1 cubic foot of feathers does not weigh the same as 1 cubic foot of gold.
the denisty of water is 1000 kilograms per cubic meter. since there are 0.3048 meters in every foot, and roughly .454 kilograms in every pound the conversion works out to 62.42796 pounds of water per every cubic foot so for 1 cubic foot of water there is 62.43 pounds.
It would weigh 1,342 pounds.
