The answer depends on the density of the rock. A cubic foot of pumice, for example, can have a mass of around 15.6 pounds whereas minerals rich in metals such as iridium will have mass exceeding 1200 pounds.
The weight of a cubic foot of rock will depend on the specific gravity and proportion of the minerals that compose the rock.
A cubic yard of crushed lava rock typically weighs around 2,750 pounds (1.375 tons).
1 cubic yard of rock = 27 cubic feet of rock. 27 cubic feet of rock @ 6" (1/2 of foot) = 27/(1/2) = 54 sf
Limestone is a type of rock, so its weight can vary from almost nothing (a small pebble) to a million or more pounds. There is not a specific size limestone, so there is no answer for this question, other than it is a type of sediment that turned into rock.
Basalt (solid)--188 pounds per cubic foot.
about 2500 pounds.

Natural rock for landscaping weighs between 1.4 and 1.7 tons
If you are going to buy river stone/pebles/rock from supplier they use the "formula" Cubic Yards x 1.25 = Weight in tons. They then sell it by the ton. (say $300 per ton) But this is an approximation. If it is one very big river rock it would be a good approximation, but even then it would depend upon the density of the rock eg granite would require a bigger constant (the 1.25) than a Sandstone boulder.
For the calculus you need the density of this rock: M = V x d.
The lightest rock on Earth is pumice, which typically has a weight of around 0.25 to 0.6 grams per cubic centimeter.
1 cubic yard of rock = 27 cubic feet of rock. 27 cubic feet of rock @ 6" (1/2 of foot) = 27/(1/2) = 54 sf
(3 x 2 x depth of the hole in feet) cubic feet
The weight of a yard of red rock can vary depending on the specific type of rock. On average, 1 cubic yard of red rock can weigh between 2,000 to 3,000 pounds or roughly 1 to 1.5 tons.
The weight of rock varies depending on its type and density, but on average, most types of rock weigh between 2,500 to 3,000 pounds per cubic yard. For example, granite typically weighs around 2,600 pounds per cubic yard, while limestone can weigh about 2,400 pounds per cubic yard. It's important to consider the specific type of rock for more accurate measurements.
The weight of a cubic meter of peridotite can vary depending on the specific composition of the rock. On average, peridotite has a density of about 3.2 - 3.4 grams per cubic centimeter, so a cubic meter would weigh around 3200 - 3400 kilograms.
