If you have measured the weight of the bar in kilograms, then divide the weight of the bar by 7850 and this will give you volume of the bar in cubic metres. Divide this volume by the length of the bar measured in metres and the result will be the area of the bar in Square Meters.

Similarly, how do you calculate area of steel?
Rectangular Steel Surface Multiply the length by the width to obtain the area of the steel in square inches. Now, for the example, you have 135 inches times 50 inches, or an area of 6,750 square inches. Divide the area by 144 to change to square feet, since 144 square inches equals one square foot.
Subsequently, question is, what is the formula for the area? Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
Hereof, how do you calculate rebar volume?
The volume of water you have to add back, is the volume of the rebar. Then calculate the the weight by multiplying the volume by the weight of mild steel per unit volume. (7.85 G/cc) now you know the weight of that length.
What is the formula of cross sectional area?
The cross sectional area of wire. Most wire is made with a circular cross section of some particular radius and diameter. The area of that cross section is the well known A = pi*R² which is colloquially pronounced as "pie are squared."

The relative cross-sectional area of steel required for typical reinforced concrete is usually quite small and varies from 1% for most beams and slabs to 6% for some columns.What is the area of a rod?
The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.How long is a ton of steel?
134 pieces of 10mm reinforcement bar will give 1 ton. 93 pieces of 12mm reinforcement bar will give 1 ton. 52 pieces of 16mm reinforcement bar will give 1 ton. 34 pieces of 20mm reinforcement bar will give 1 ton.How do you find the density of steel?
We calculate the density of metal by dividing the mass of the object by its volume. Suppose the mass of the object is 7.952 pounds and its volume is 28 cubic inches then its density would be 0.284 per cubic inch.What is cross section area?
Cross-sectional area. The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object - such as a cylinder - is sliced perpendicular to some specified axis at a point. For example, the cross-section of a cylinder - when sliced parallel to its base - is a circle.How do you calculate the volume of a steel bar?
here is the process of derivation.- assume a steel bar with length equals L and dia equals D.
- remember: Weight = volume x unit weight. or W = V x ?
- here V is the volume so the volume of round steel bar can be writen as pD^2/4 x length of the bar.
- convert the dia into meters from mm.
What is the area and volume of a cylinder?
The formula for the volume of a rectangular solid, V=Bh V = B h , can also be used to find the volume of a cylinder. For the rectangular solid, the area of the base, B , is the area of the rectangular base, length × width. For a cylinder, the area of the base, B , is the area of its circular base, πr2 π r 2 .What is a formula of cylinder?
It is given by the formula, πr2h, where r is the radius of the circular base and h is the height of the cylinder.How do you find the area of a sphere?

How fo you find the volume of a pyramid?
To calculate the volume of a pyramid with a rectangular base, find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Take that result and divide it by 3 to calculate the pyramid's volume!How do you find the area of a tube?
Plug in L and D into the following equation to calculate the surface area of the pipe: 3.14 x L x D. For example, if you had a pipe with a length of 20 feet and a diameter of 2 feet, you would get 3.14 x 20 x 2 and find that the surface area of the pipe equals 125.6 square feet.What's the volume of a cube?
Volume is measured in "cubic" units. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.How do I find the volume?
Units of Measure- Volume = length x width x height.
- You only need to know one side to figure out the volume of a cube.
- The units of measure for volume are cubic units.
- Volume is in three-dimensions.
- You can multiply the sides in any order.
- Which side you call length, width, or height doesn't matter.
Do you need rebar for 4 inch slab?
A concrete slab reinforced with rebar or welded wire fabric should have a minimum 1 1/2 inches of clear cover between the reinforcing and the top of the slab. On grade you can get away with welded wire fabric in most instances. Suspended slabs almost always require rebar reinforcing.Where should rebar be placed in a slab?
Therefore, for a typical 100 mm residential concrete slab, the rebar should be placed at a depth of approximately two thirds the slab thickness from its surface. Placing the rebar at the bottom of the slab will provide no benefit to the concrete.How many sticks of rebar are in a ton?
Cost Per Ton One ton of rebar can contain a varying number of sticks depending on the thickness. These calculations are of the number of 20-foot sticks of rebar in one ton, based on how much one stick weighs.What does 10m rebar weigh?
