Question

find the volume of the rectangular prism.

8.5 in.
6 in.
6.5 in.

enter the correct answer in the box.

□ in³

(the number pad is shown at the bottom, but it is not relevant to the text of the problem itself.)

Explanation:

Step1: 确定体积公式

长方体体积公式为$V = l \times w \times h$，其中$l=6\ \text{in}$，$w=6.5\ \text{in}$，$h=8.5\ \text{in}$。

Step2: 计算长×宽

$$\begin{aligned} l \times w &= 6 \times 6.5 \\ &= 39 \end{aligned}$$

Step3: 计算总体积

$$\begin{aligned} V &= 39 \times 8.5 \\ &= 331.5 \end{aligned}$$

Answer:

331.5
