Surface Area of a Rectangular Prism

Front

What is the surface area of a rectangular prism?

Back

The total area of all the surfaces of a rectangular prism, calculated using the formula: Surface Area = 2lw + 2lh + 2hw.

Front

What is the formula to find the surface area of a rectangular prism?

Back

Surface Area = 2lw + 2lh + 2hw, 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) + 2(5)(4) + 2(3)(4) = 30 + 40 + 24 = 94 cm².

Front

What units are used to measure surface area?

Back

Square units, such as cm², m², ft², in².

Front

How do you calculate 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 ft, 3 ft, and 4 ft?

Back

Surface Area = 2(2)(3) + 2(2)(4) + 2(3)(4) = 12 + 16 + 24 = 52 ft².

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 surface area of a rectangular prism with a length of 7 in, width of 5 in, and height of 3 in?

Back

Surface Area = 2(7)(5) + 2(7)(3) + 2(5)(3) = 70 + 42 + 30 = 142 in².

Front

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

Back

The surface area is directly related to the dimensions; increasing any dimension increases the surface area.

Front

How do you find the surface area of a rectangular prism if you only know the volume?

Back

You need at least one dimension (length, width, or height) to find the surface area from the volume.
