Surface Area of a Rectangular Prism

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

If a rectangular prism has a length of 5 cm, width of 3 cm, and height of 4 cm, what is its surface area?

Back

Surface Area = 2(5*3 + 5*4 + 3*4) = 2(15 + 20 + 12) = 2(47) = 94 cm².

Front

What does 'surface area' mean in geometry?

Back

Surface area is the total area of the surface of a three-dimensional object.

Front

How do you find the area of one face of a rectangular prism?

Back

Area of one face = length × width.

Front

What is the surface area of a rectangular prism with dimensions 2 m, 3 m, and 4 m?

Back

Surface Area = 2(2*3 + 2*4 + 3*4) = 2(6 + 8 + 12) = 2(26) = 52 m².

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.

Front

What is the unit of measurement for surface area?

Back

Square units (e.g., cm², m², ft², in²).

Front

What is the surface area of a rectangular prism with a length of 10 ft, width of 5 ft, and height of 2 ft?

Back

Surface Area = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160 ft².

Front

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

Back

The surface area depends on the length, width, and height; changing any dimension affects the total surface area.

Front

How do you calculate the surface area of a cube?

Back

Surface Area = 6a², where a = length of one side.
