Surface Area of 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

What does 'surface area' mean?

Back

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

Front

If a rectangular prism has a length of 5 feet, width of 3 feet, and height of 2 feet, what is its surface area?

Back

Surface Area = 2(5*3 + 5*2 + 3*2) = 62 square feet.

Front

What units are used to measure surface area?

Back

Square units (e.g., square feet, square meters, square inches).

Front

How does increasing the dimensions of a rectangular prism affect its surface area?

Back

Increasing any dimension (length, width, or height) will increase the surface area.

Front

What is the surface area of a rectangular prism with dimensions 10 cm long, 4 cm wide, and 5 cm high?

Back

Surface Area = 2(10*4 + 10*5 + 4*5) = 180 square cm.

Front

What is the surface area of a cube with a side length of 6 inches?

Back

Surface Area = 6 * (side length)^2 = 6 * (6)^2 = 216 square inches.

Front

If the length of a rectangular prism is doubled, how does that affect the surface area?

Back

The surface area will increase, specifically it will become 2 times the original surface area plus the area of the new dimensions.

Front

What is the surface area of a rectangular prism with dimensions 8 m long, 3 m wide, and 2 m high?

Back

Surface Area = 2(8*3 + 8*2 + 3*2) = 66 square meters.

Front

What is the relationship between volume and surface area in a rectangular prism?

Back

Volume measures the space inside the prism, while surface area measures the area covering the outside.
