6th Surface area of rectangular prisms

Front

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

Back

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

Front

What does surface area represent in a 3D shape?

Back

The sum of the areas of all the surfaces (faces) of a 3D shape.

Front

If a rectangular prism has dimensions 2 cm, 3 cm, and 4 cm, what is its surface area?

Back

52 cm².

Front

What is a rectangular prism?

Back

A 3D shape with 6 rectangular faces.

Front

How many faces does a rectangular prism have?

Back

6 faces.

Front

What is the surface area of a rectangular prism with a length of 5 m, width of 3 m, and height of 2 m?

Back

62 m².

Front

What is the relationship between the dimensions of a rectangular prism and its surface area?

Back

The surface area increases as the dimensions (length, width, height) increase.

Front

What is the surface area of a cube with a side length of 4 cm?

Back

96 cm² (Surface Area = 6s², where s = side length).

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface, while volume measures the space inside the 3D shape.

Front

If the dimensions of a rectangular prism are doubled, how does the surface area change?

Back

The surface area increases by a factor of 4.
