Question

the prisms that go across the top (called lintels) are 16 feet long, 3 feet high, and 3 feet wide. what is the volume of one of the lintels? ? cubic feet

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

For the lintel, \( l = 16 \) feet, \( w = 3 \) feet, \( h = 3 \) feet.

Step3: Calculate volume

Substitute values into the formula: \( V = 16 \times 3 \times 3 \). First, \( 3 \times 3 = 9 \), then \( 16 \times 9 = 144 \).

Answer:

144
