Question

what is the volume of the right rectangular prism with a length of 18 inches, a width of 4 inches, and a height of 10 inches?
○ 22 in³
○ 64 in³
○ 720 in³
○ 1,440 in³

Explanation:

Step1: Recall Volume Formula

The volume \( V \) of a right rectangular prism is given by \( V = l \times w \times h \), where \( l \) is length, \( w \) is width, and \( h \) is height.

Step2: Substitute Values

Given \( l = 18 \) in, \( w = 4 \) in, \( h = 10 \) in. Substitute into the formula: \( V = 18 \times 4 \times 10 \).

Step3: Calculate Product

First, \( 18 \times 4 = 72 \), then \( 72 \times 10 = 720 \).

Answer:

720 in³ (corresponding to the option with 720 in³)
