Surface Area Rectangular Prisms

Front

What is the definition of Surface Area?

Back

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

Front

What is the formula for the Surface Area of a Rectangular Prism?

Back

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

Front

What is Lateral Surface Area?

Back

Lateral Surface Area is the area of all the sides of a prism, excluding the top and bottom faces.

Front

How do you calculate 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 5 cm, width of 3 cm, and height of 4 cm, what is its Surface Area?

Back

Surface Area = 2(5*3 + 5*4 + 3*4) = 2(15 + 20 + 12) = 2(47) = 94 cm².

Front

What is the Surface Area of a Cube?

Back

The Surface Area of a Cube is 6a², where a is the length of a side.

Front

If a cube has a side length of 10 inches, what is its Surface Area?

Back

Surface Area = 6(10)² = 6(100) = 600 in².

Front

What is the relationship between the Surface Area and Volume of a Rectangular Prism?

Back

Surface Area measures the total area of the surface, while Volume measures the space inside the prism.

Front

How do you find the Volume of a Rectangular Prism?

Back

Volume = l × w × h, where l = length, w = width, h = height.

Front

What is the Surface Area of a rectangular prism with dimensions 2 m x 3 m x 4 m?

Back

Surface Area = 2(2*3 + 2*4 + 3*4) = 2(6 + 8 + 12) = 2(26) = 52 m².
