Surface Area Introduction

Front

What is the definition of surface area?

Back

The sum of all the areas of all the shapes that cover the object.

Front

What 3D solid does a triangular prism have?

Back

A triangular prism is a 3D solid with two triangular bases and three rectangular faces.

Front

How do you calculate the surface area of a triangular prism?

Back

To calculate the surface area of a triangular prism, add the areas of the two triangular bases and the three rectangular faces.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

What is the unit of measurement for surface area?

Back

Surface area is typically measured in square units, such as square inches (in²), square centimeters (cm²), or square meters (m²).

Front

If the surface area of a triangular prism is 170 cm², what does this represent?

Back

This represents the total area of all the surfaces of the triangular prism.

Front

What is the surface area of a rectangular face of a prism?

Back

The surface area of a rectangular face is calculated by multiplying its length by its width.

Front

How do you find the surface area of a cylinder?

Back

The surface area of a cylinder is calculated using the formula: Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is the relationship between surface area and volume in 3D shapes?

Back

Surface area measures the total area of the surface, while volume measures the space contained within the shape. They are related but represent different properties.
