Surface Area of rectangular and Triangular Prisms

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the formula for the surface area of a triangular prism?

Back

Surface Area = bh + lP, where b = base, h = height of the triangle, l = length of the prism, P = perimeter of the triangle's base.

Front

How many faces does a triangular prism have?

Back

5 faces.

Front

How many faces does a rectangular prism have?

Back

6 faces.

Front

What is the surface area of a prism?

Back

The total area of all the surfaces of the prism.

Front

What is the difference between lateral surface area and total surface area?

Back

Lateral surface area is the area of the sides only, while total surface area includes the bases.

Front

If the length of a rectangular prism is doubled, how does the surface area change?

Back

The surface area increases, as it depends on the dimensions of the prism.

Front

What units are used to measure surface area?

Back

Square units (e.g., cm², m², in²).

Front

What is the perimeter of a triangle?

Back

The sum of the lengths of all three sides of the triangle.

Front

How do you find the area of a triangle?

Back

Area = 1/2 * base * height.
