Front

What is the area of the base in geometry?

Back

The area of the base refers to the amount of space inside the base shape, calculated using the appropriate formula (e.g., length x width for rectangles).

Front

What is a function in mathematics?

Back

A function is a relation where each input (x) has exactly one output (y). This means x cannot repeat for different y values.

Front

What does it mean for a line to be proportional?

Front

What is lateral surface area?

Back

Lateral surface area is the area of just the sides of a three-dimensional shape, excluding the top and bottom surfaces.

Front

What is the formula for the area of a rectangle?

Back

Area = length x width.

Front

What is the formula for the volume of a rectangular prism?

Back

Volume = length x width x height.

Front

What is the difference between area and surface area?

Back

Area refers to the space within a two-dimensional shape, while surface area refers to the total area of the outer surfaces of a three-dimensional object.

Front

What is a proportional relationship?

Back

A proportional relationship is one where two quantities maintain a constant ratio or relationship to each other.

Front

What is the formula for the perimeter of a rectangle?
