Surface Area of Rectangular Prisms

Front

What is the difference between lateral area and total surface area?

Back

Total surface area includes the base(s) and all the faces while lateral does not include the base(s).

Front

What does surface area represent in a 3-dimensional shape?

Back

Surface area represents wrapping the outside of a 3-dimensional shape.

Front

What do we call a 2-dimensional representation of a 3-dimensional object?

Back

Front

What is surface area?

Back

The sum of all the areas of all the shapes that cover the object.

Front

A cube's side length measures 15 inches. What is the surface area of the cube?

Back

1350 in².

Front

How do you calculate the surface area of a rectangular prism?

Back

Surface Area = 2lw + 2lh + 2wh, where l = length, w = width, h = height.

Front

What is the lateral surface area of a rectangular prism?

Back

Lateral Surface Area = 2h(l + w), where h = height, l = length, w = width.

Front

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

Back

Total Surface Area = 2(4*3 + 4*5 + 3*5) = 94 cm².

Front

What is the formula for the surface area of a cube?

Back

Surface Area = 6s², where s = side length.

Front

What is the relationship between surface area and volume in 3-dimensional shapes?

Back

Surface area measures the exterior, while volume measures the interior space.
