Lead has a higher density than concrete, so a 1"x1"x1" cube of concrete would weigh less than the same cube of lead.
They both weigh one pound.
Yes, lead is a lot heavier than concreate
they are equal weight of course
Ten grams of lead.
They both have the same value
No. Density says how much it weighs per volume unit, like kilo per liter.An example is that lead has higher density than water (weighs more per liter), but a lot of water still weighs more (is more massive) than a little lead.
They both weigh the same.
Concrete
dry concrete
Wet concrete weighs about 4,000 per cubic yard. Some types of concrete weigh more or less. Lightweight concrete weighs about 1,000 pounds less.
they are equal weight of course
A square inch of lead because lead is more dense
concrete 2400 Kg/m3aluminun 2712 Kg/m3
lead which is element of non metal is heavier than air
Ten grams of lead.
They both have the same value
That depends on what substance is in the 20 gallons. A gallon is a unit of volume, or capacity, or space. It it's 20 gallons of air, it weighs very few pounds. If it's 20 gallons of water, it weighs about 167 pounds. If it's 20 gallons of stones or concrete or lead, it weighs a lot more pounds. If it's 20 completely empty gallons, it weighs no pounds at all.

Wet concrete weighs approximately 4,000 pounds per square yard. That amount varies depending on the water content. Lightweight concrete weighs about 1,000 pounds less.
