A 2 by 4 (lumber) will have a weight based on the density of the wood. Pine, fir, redwood, treated or untreated will have different densities.
It depends. They weigh equally if 2 blocks weigh as much as 1 marble. If 2 blocks are heavier, 10 blocks > 5 marbles If 1 marble is heavier, 10 blocks < 5 marbles
You do not have enough information to come up with an accurate answer. All wood does not weigh the same.
If five circles weigh 10 pounds, then each 2 squares are going to weigh 25, because 10+10+10+10+10= 50 that was 5 tens. Then 2 square 50 รท 2= 25. So 25+25= 50. It took me 10 minutes to get that answer
