## How do you find the volume of a isosceles trapezoidal prism?

Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

## How do you find the area of a isosceles trapezoid prism?

To find the surface area of an isosceles trapezoidal prism,

- Step 1: Find perimeter: The perimeter of the base of the trapezoidal prism is the sum of the lengths of the sides.
- Step 2: The base is an isosceles trapezoid, thus its area B is 1/2h(b1+b2).
- Step 3: Put the values in the formula, T.S.A. = PH+2B.

**What is the altitude of a trapezoidal prism?**

The altitude is the distance between the base (bottom) and the top of the trapezoid. The altitude of a trapezoid is simply its height.

**How do you find the volume of prisms?**

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

### What is the formula for 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.

### What is a right trapezoidal prism?

A trapezoidal prism is a three-dimensional solid made up of two trapezoids on opposite faces joined by four rectangles called the lateral faces.

**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.

**What is the altitude of an isosceles trapezoid?**
