Question

decide if this biconditional statement is true or false.
an object is 3 - dimensional if and only if it has height, width, and depth.
true
false

Explanation:

Step1: Analyze the definition of 3 - dimensional

A 3 - dimensional object is defined by having three dimensions: height, width, and depth.

Step2: Check the biconditional statement

The biconditional statement says "An object is 3 - dimensional if and only if it has height, width, and depth". The "if and only if" means that having height, width, and depth is both a necessary and sufficient condition for an object to be 3 - dimensional. Since the definition of a 3 - dimensional object matches the right - hand side of the biconditional, the statement is True.

Answer:

True
