Front

What is surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies, measured in square units.

Front

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

Back

To calculate the surface area of a rectangular prism, use the formula: SA = 2(lw + lh + wh), where l = length, w = width, and h = height.

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional figure that can be folded to form the figure.

Which figure does this net represent? (Image of a net for a rectangular prism)

Back

Rectangular Prism

Front

What is the surface area of a cube with a side length of 5 inches?

Back

The surface area is 150 square inches, calculated using the formula SA = 6s², where s = side length.

Front

How do you find the surface area of a triangular prism?

Back

To find the surface area of a triangular prism, use the formula: SA = bh + (perimeter of base * height), where b = base area and h = height of the prism.

Front

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

Back

The surface area of a cylinder is given by the formula: SA = 2πr(h + r), where r = radius and h = height.

Front

What is the surface area of a sphere?

Back

The surface area of a sphere is calculated using the formula: SA = 4πr², where r = radius.

Front

How do you convert square inches to square feet?

Back

To convert square inches to square feet, divide the number of square inches by 144 (since 1 square foot = 144 square inches).

Front

What is the surface area of a rectangular prism with dimensions 3 ft, 4 ft, and 5 ft?

Back

The surface area is 94 square feet, calculated using the formula SA = 2(lw + lh + wh).
