Question

determine which values represent volume. a) 129 in² b) 3 ft³ c) 4 yd³ d) 88 in² how do you know is a value is volume?

Explanation:

Volume is a 3-dimensional measurement, so it uses cubic units (units raised to the power of 3). Area uses square units (units raised to the power of 2). We identify values with cubic units.

Answer:

b) $3\ \text{ft}^3$
c) $4\ \text{yd}^3$

To determine a value is volume: Volume measures the space inside a 3D object, so it is expressed in cubic units (units with an exponent of 3, e.g., $\text{ft}^3$, $\text{yd}^3$), unlike area which uses square units ($\text{in}^2$).
