Question

select the correct answer. firewood can be sold in cords. the wood is cut into equal lengths and stacked evenly in a rack. which geometric shape can be used as a model to calculate the volume of the cord of wood? a. pyramid b. cylinder c. cone d. rectangular prism

Explanation:

Step1: Recall volume formulas

Volume of pyramid $V=\frac{1}{3}Bh$ (where $B$ is base - area and $h$ is height), volume of cylinder $V = \pi r^{2}h$, volume of cone $V=\frac{1}{3}\pi r^{2}h$, volume of rectangular prism $V = lwh$. Firewood is stacked in a rectangular - like shape in a rack.

Step2: Match with real - life situation

Rectangular prism is the most appropriate geometric shape to model the stacked firewood as it has a rectangular base and height, similar to how firewood is arranged in a rack.

Answer:

D. rectangular prism
