Surface Area- Rectangular Prisms #1

Front

What is the formula to calculate 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 9 cm, and height of 20 cm, what is its surface area?

Back

650 cm²

Front

What does surface area represent in a three-dimensional shape?

Back

Surface area represents the total area of the outer surface of a three-dimensional shape.

Front

How do you find the area of a rectangle?

Back

Area = Length × Width.

Front

Which of the following requires finding surface area? Finding out how much wrapping paper is needed to cover a present or finding out how much water will fill a cylinder?

Back

Finding out how much wrapping paper is needed to cover a present.

Front

What is the surface area of a rectangular prism with dimensions: length = 9 m, height = 10 m, width = 12 m?

Back

636 m²

Front

What is the height of a rectangular prism if its surface area is 600 cm², length is 10 cm, and width is 5 cm?

Back

Height = 6 cm (using the formula: 600 = 2(10*5 + 10*h + 5*h)).

Front

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

Back

Surface Area = 6 × (side length)² = 6 × (4 cm)² = 96 cm².

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).
