What Is a Prism?

A prism is a three-dimensional geometric solid with:

• Two identical and parallel bases
• Rectangular or parallelogram side faces
• Uniform cross-section throughout its length

Common prism types include:

• Rectangular prism
• Triangular prism
• Square prism
• Hexagonal prism

Each prism has two main measurements:

1. Base area
2. Height (length between bases)

What Does the Surface Area Prism Calculator Do?

The calculator computes the Total Surface Area (TSA) of a prism.

Required Inputs:

• Perimeter of base (P)
• Area of base (B)
• Height of prism (h)

Output:

• Total Surface Area (TSA)

---

Surface Area Formula for a Prism

The correct formula used is:$$\textbf{Surface Area} = 2B + Ph$$Surface Area=2B+Ph

Where:

• B = Area of the base
• P = Perimeter of the base
• h = Height of the prism

This formula works for all types of prisms as long as the base area and perimeter are correctly calculated.

How to Use the Surface Area Prism Calculator

Using the calculator is simple:

Step 1: Enter Base Area (B)

Input the area of the prism’s base.

Step 2: Enter Base Perimeter (P)

Provide the total perimeter of the base.

Step 3: Enter Height (h)

Enter the vertical distance between the two bases.

Step 4: Click Calculate

The calculator instantly shows the total surface area.

Practical Example

Let’s say we have a triangular prism:

• Base area = 20 cm²
• Base perimeter = 18 cm
• Height = 10 cm

Using the formula:

Surface Area = 2(20) + (18 × 10)
Surface Area = 40 + 180
Surface Area = 220 cm²

The calculator performs this instantly and accurately.

Surface Area vs Lateral Surface Area

It’s important to understand:

• Total Surface Area (TSA) includes bases + side faces
• Lateral Surface Area (LSA) includes only side faces

Lateral Surface Area formula:$$LSA = Ph$$LSA=Ph

Our calculator specifically provides Total Surface Area.
