Help needed to calculate soil weight in boxes
I am trying to calculate what the weight of soil would be (wet) with box dimensions of 8ft x 3ft x 2ft with the depth of soil being 2 1/2 ft. The box will be a new fibreglass substance and I can calcualte the weight of that myself.
I need this info for a structural engineer so we can see of a garage roof can handle 4 of these sitting on a double span on the roof.
Soil will be regular garden soil with home made compost..not a lighter weight bagged soil.
Any help would be much appreciated
