When simplified is A = A(lateral) + 2 * A(base) How to find the surface area of a cylinder? Therefore, the final formula to use to find a triangular prism’s surface area is:Ī = h * (a + b + c) + 0.5 * √((a + b + c) * (-a + b + c) * (a – b + c) * (a + b – c)) One of the most common methods is to use Heron’s formula which is typically used when you have the values for all three sides of the triangle. There are several ways to do this depending on the value you have. P refers to the perimeter of the base triangleĪfter this, it’s time to calculate the area of the triangular base. Therefore, the formula is:Ī(lateral) = a * h + b * h + c * h = h * (a + b + c) For this shape, the lateral surface area is quite easy to calculate as it’s made up of 3 rectangles which have one length of the side in common. When simplified is A = 2 * (A1 + A2 + A3) How to find the surface area of a triangular prism?īefore we go to the formula for the surface area of a triangular prism, you must first understand where it’s derived. To find the surface area of a rectangular prism, first perform the calculations to find the areas of the rectangular sides:

You can use it to find the surface area of the most common shapes. This is why the surface area calculator is so useful. When you learn how to calculate surface area, this applies to different shapes. How to find the surface area of a rectangular prism?

The calculator then generates for you the value of the Surface Area along with an illustration of the shape you have chosen.

Then enter the value of the Length and choose the unit of measurement from the drop-down menu.

First, choose the Shape from the drop-down menu.

Here are the steps to follow for this online tool: Use it to check your answer or use it to perform the calculation for you. When you’re learning how to calculate surface area, this surface area calculator comes in handy.
