## How do you find the surface area and volume of a trapezoidal prism?

The surface area of a trapezoidal prism can be given with this formula: (b1+b2)h + PH. In this formula, “b1” and “b2” stand for the length of the bases of the trapezoid. The height of the trapezoid is “h”. The perimeter of the trapezoid is “P”, and “H” is the height of the prism.

### What’s the formula for volume of a prism?

V=Bh

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm. The area A of a rectangle with length l and width w is A=lw .

#### What is the area of a trapezoidal prism?

The length of the four rectangles will be the sum of the four sides of the trapezoid, the two bases, and the other two sides. The surface area can be given with this formula: Surface Area of Trapezoidal Prism = (b1+b2)h + PH. In this formula, b1 and b2 stand for the length of the bases of the trapezoid.

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

Explanation: To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

**What is trapezoidal prism?**

A trapezoidal prism is a three dimensional solid that has two congruent trapezoids for its top and lower base. It will have four rectangles that connect the corresponding sides of the two bases. These four rectangles are called the lateral faces of the prism.

## How do you calculate the square footage of a trapezoid?

In this case you need the top edge, bottom edge, left side, right side. The formula for a trapezoid is: Square footage Trapezoid= Height* (top edge + bottom edge)/2.

The surface area of a trapezoid is calculated using the equation 1/2(a+b)*h, where “a” and “b” are the parallel sides of the trapezoid, and “h” is the vertical height. For example, if side “a” equals three, side “b” equals five and height “h” equals four, then the area equals 1/2(3+5)*4, or 16.

### How do you calculate the surface area of a prism?

The surface area on the length of the prism is then calculated by taking the perimeter of the shape on the ‘cut’ face of the prism, and multiplying it by the length of the prism. By summing these two areas, you will obtain the total surface area.

#### How do you calculate the sides of a trapezoid?

A trapezoid is a quadrilateral that has only one pair of sides that are parallel. To calculate the area of trapezoids, take the average of bases and multiply by its height. The area of a trapezoid is given by: A = (a + b) ∙ h /2.
