Question

find the volume of the rectangular prism. 3 cm 9 cm 7 cm v = ? cm³

Explanation:

Step1: Recall volume formula for rectangular prism

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

Step2: Identify dimensions

From the diagram, \( l = 7 \, \text{cm} \), \( w = 9 \, \text{cm} \), \( h = 3 \, \text{cm} \).

Step3: Calculate volume

Substitute the values into the formula: \( V = 7 \times 9 \times 3 \). First, \( 7 \times 9 = 63 \), then \( 63 \times 3 = 189 \).

Answer:

189
