Nets and Surface Area of Rectangular Prisms

Front

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

Back

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

Front

What are the dimensions of a rectangular prism?

Back

A rectangular prism has three dimensions: length (l), width (w), and height (h).

Front

How do you find the surface area of a rectangular prism with dimensions 2 cm, 3 cm, and 4 cm?

Back

Using the formula SA = 2(lw + lh + wh), substitute the values: SA = 2(2*3 + 2*4 + 3*4) = 2(6 + 8 + 12) = 2(26) = 52 cm².

Front

What is a net in the context of a rectangular prism?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape. For a rectangular prism, the net consists of six rectangles.

Front

What is the surface area of a rectangular prism with a surface area of 444 in²?

Back

The surface area is already given as 444 in².

Front

What is the significance of surface area in real-life applications?

Back

Surface area is important in real-life applications such as determining the amount of material needed to cover an object, like wrapping paper for a gift.

Front

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

Back

The surface area of a rectangular prism increases with the increase in any of its dimensions (length, width, or height).

Front

How can you visualize the surface area of a rectangular prism?

Back

You can visualize the surface area by imagining the total area of all the faces of the prism, which can be represented by its net.

Front

What is the surface area of a rectangular prism with dimensions 10 cm, 10 cm, and 8 cm?

Back

Using the formula SA = 2(lw + lh + wh), SA = 2(10*10 + 10*8 + 10*8) = 2(100 + 80 + 80) = 2(260) = 520 cm².

Front

What type of solid does a net with rectangles create?

Back

A net made up of rectangles creates a rectangular prism.
