Surface Area and Composite Area

Front

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

Back

Lateral Surface Area = 2h(l + w), where h is height, l is length, and w is width.

Front

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

Back

Lateral Surface Area = (Perimeter of base) * height.

Front

Define composite area.

Back

Composite area is the total area of a shape made up of two or more simple shapes.

Front

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

Back

Total Surface Area = Lateral Surface Area + 2 * Area of the base.

Front

How do you find the area of a shaded region?

Back

Area of shaded region = Total area of the larger shape - Area of the unshaded region.

Front

What is the area of a rectangle?

Back

Area = length * width.

Front

What is the area of a triangle?

Back

Area = 1/2 * base * height.

Front

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

Back

Lateral surface area excludes the area of the bases, while total surface area includes the area of the bases.

Front

How do you calculate the perimeter of a triangle?

Back

Perimeter = sum of the lengths of all three sides.

Front

What is the height of a prism?

Back

Height is the perpendicular distance between the two bases of the prism.
