6th Surface area of rectangular prisms

Front

What is the surface area of a rectangular prism?

Back

The sum of the areas of all the surfaces (faces) of a rectangular prism.

Front

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

Back

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

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

If a rectangular prism has dimensions 2 cm, 3 cm, and 4 cm, what is its surface area?

Back

Surface Area = 2(2*3 + 2*4 + 3*4) = 52 cm².

Front

What is a net of a 3D shape?

Back

A net is a 2D representation of a 3D shape that can be folded to form the shape.

Front

What 3D solid does a net with 6 rectangles create?

Back

Rectangular Prism.

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surfaces, while volume measures the space inside the 3D shape.

Front

What is the surface area of a rectangular prism with dimensions 5 cm, 6 cm, and 7 cm?

Back

Surface Area = 2(5*6 + 5*7 + 6*7) = 2(30 + 35 + 42) = 2(107) = 214 cm².

Front

What is the unit of measurement for surface area?

Back

Square units (e.g., cm², m², in²).

Front

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

Back

The surface area increases, as it depends on the dimensions of the prism.
