How many cans would I need for 100 sq.ft. of surface area?

Answer 1

First, it depends on the size of the can. Take the measurement of the diameter of the can (how many inches across). Next, figure out how many cans would fit in 1 sq.ft.(12in. x 12in.). For instance, if the can measures 3 in. across then we will be able to fit 4 cans length-wise and 4 cans width-wise. The formula for sq.footage is length x width. 4 x 4 = 16. So 16 cans will fill 1 sq.ft. Now multiply that by 100: you'll need 1600 cans.
