Surface Area Of Rectangular Prisms

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

How many faces does a rectangular prism have?

Back

A rectangular prism has 6 faces.

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 a rectangular prism has a length of 10 cm, width of 5 cm, and height of 2 cm, what is its surface area?

Back

Surface Area = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160 cm².

Front

What is the surface area of a rectangular brick with dimensions 5 cm x 9 cm x 20 cm?

Back

Surface Area = 650 cm².

Front

What does 'surface area' refer to in geometry?

Back

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

Front

How do you find the surface area of a cylinder?

Back

Surface Area = 2πr(h + r), where r = radius and h = height.

Front

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

Back

Surface area measures the total area of the outside, while volume measures the space inside.

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 surface area of a rectangular prism with a length of 3 m, width of 4 m, and height of 5 m?

Back

Surface Area = 2(3*4 + 3*5 + 4*5) = 2(12 + 15 + 20) = 2(47) = 94 m².
