3.5 Surface Area of Prisms and Cylinders

Front

What is the formula for the total surface area of a cylinder?

Back

The total surface area (SA) of a cylinder is given by the formula: SA = 2\pi r(h + r), where r is the radius and h is the height.

Front

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

Back

The total surface area (SA) of a rectangular prism is given by the formula: SA = 2(lw + lh + wh), where l is the length, w is the width, and h is the height.

Back

The total surface area is 125.6 cm².

Front

What is the lateral surface area of a cylinder?

Back

The lateral surface area (LSA) of a cylinder is given by the formula: LSA = 2\pi rh, where r is the radius and h is the height.

Front

Front

What is the difference between total surface area and lateral surface area of a cylinder?

Back

Total surface area includes the areas of the two circular bases and the lateral area, while lateral surface area only includes the area around the sides.

Front

What units are used for measuring surface area?

Back

Surface area is measured in square units, such as cm², m², etc.
