Surface Area and Volume of 3-D Figures

Front

What is the formula for the surface area of a triangular prism?

Back

Surface Area = (Base Area x 2) + (Perimeter of Base x Height)

Front

Define surface area.

Back

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

Front

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

Back

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

Front

What does 'volume' refer to in geometry?

Back

Volume is the amount of space occupied by a three-dimensional object.

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

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

Back

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

Front

What is the significance of using 3.14 instead of π in calculations?

Back

Using 3.14 is an approximation of π, which simplifies calculations but may reduce accuracy.

Front

What is the surface area of a cylinder with a radius of 5 cm and height of 10 cm?

Back

Surface Area = 2π(5)(10 + 5) = 471.24 cm².

Front

What is the volume of a triangular prism with a base area of 20 cm² and height of 10 cm?

Back

Volume = Base Area x Height = 20 cm² x 10 cm = 200 cm³.

Front

How do you find the surface area of a sphere?

Back

Surface Area = 4πr², where r is the radius.
