# How do you find the area of a trapezoidal rule?

## How do you find the area of a trapezoidal rule?

How to Apply Trapezoidal Rule?

- Step 1: Note down the number of sub-intervals, “n” and intervals “a” and “b”.
- Step 2: Apply the formula to calculate the sub-interval width, h (or) △x = (b – a)/n.
- Step 3: Substitute the obtained values in the trapezoidal rule formula to find the approximate area of the given curve,

## How do you find the volume of a trapezoidal rule?

The trapezoidal rule If we divide the length into 10 equally sized sections, then the length of each section is h = L/10, where L is the length of the ship. and so on. The above formula is called the Trapezoidal rule of integration to get the volume of the hull.

**What is the formula of trapezoidal?**

The formula that is used to find the area of a trapezoid is expressed as, Area of trapezoid = ½ (a + b) h; where a’ and ‘b’ are the bases (parallel sides) and ‘h’ is the height of the trapezoid.

### How do I find the volume?

To find the volume of a box, simply multiply length, width, and height — and you’re good to go! For example, if a box is 5×7×2 cm, then the volume of a box is 70 cubic centimeters.

### How do I calculate the volume of my pool?

Length x width x depth x 7.5 = volume (in gallons) Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool, expressed in gallons.

**How do I calculate the volume of water in my pond?**

Use our handy calculator to work out your pond capacity.

- The easiest way to do this is to measure the length, the width and the depth of your pond in feet.
- Once you have all three dimensions, you need to multiply these all together and then multiply this calculation by 6.25.
- Pond Water in Litres.

#### How do you measure the size of a pond?

Multiply the length times the width to get the square feet of surface area. This value can be converted to acres by dividing by 43,560 ft2/acre. So, a pond that measures 150 feet long and 100 feet wide would have an area = 150 feet X 100 feet = 15,000 ft2 or 0.34 acres.

#### How do you calculate gallons in a pond?

Next use following formulas to calculate the size of your pond: Square/ Rectangular (Gallons): Assume the pond averages are 8 feet by 4 feet and averages 2 feet deep. Multiply average length (feet) x average width (feet) x average water depth (feet) x 7.48 gallons per cubic foot.

**How do you calculate the volume of a pond in litres?**

Pond Water in Litres If you require this capacity in litres which most companies now work with, you will need to multiply the number of gallons by 4.5. e.g. calculate the number of litres by knowing the pond is 1,250 gallons: 1,250 x 4.5 = 5,625 litres.

## What is the volume of water in a pond?

Divide the diameter (in feet) by 2 to get the radius. (Radius = ½ Diameter). Then multiply the radius x itself x 3.14 (Pi) x the average water depth (feet) x 7.48 gallons per cubic foot.

## How do you calculate the volume of a round pond?

If you pond is 2.5m long and 1.2m wide and about 40cm deep, you would then do the following using the formula (W x L x average depth x 1000) 1.2 x 2.5 x 0.4 x 1000 = 1200 litres. When calculating the volume of a cylinder, R refers to the radius.

**How do you calculate the area of a trapezoid?**

The area of this shape is best estimated using a formula for a trapezoid by taking the average length of the two unequal sides and multiplying by the width of the pond. For example, a pond that is 200 feet long on one side, 300 feet long on the opposite side, and 100 feet wide would have an area = 250 feet X 100 feet = 25,000 ft2 or 0.57 acres.

### What is the use of trapezoidal rule?

Trapezoidal Rule Definition Trapezoidal Rule is a rule that evaluates the area under the curves by dividing the total area into smaller trapezoids rather than using rectangles. This integration works by approximating the region under the graph of a function as a trapezoid, and it calculates the area.

### How do you calculate pond volume in feet?

The volume of water in the pond (in acre-feet) is calculated by simply multiplying the pond area (in acres) by the average pond depth in feet. Keep in mind that one acre-foot of water is equal to 325,851 gallons.

**How do you estimate the shape of a peripheral pond?**

pond shape can be estimated by measuring the distance around the pond shoreline in feet. Square the shoreline distance and divide by 547,390 to get the pond area in acres.
