Question

The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown.

A trapezoid has a base of 3 inches, height of 1 inches, and top side length of 1 inch.

What is the area of one trapezoidal face of the figure?

Answer 1

The trapezoid face of a figure will also be known as the trapezoid area.

Trapezoid area formula:

(base1 + base2)/2 * height

Let’s plug in some values

(3 + 1)/2 * 1
(4)/2 * 1
2 * 1
2

The area of the trapezoidal face would be 2 in^2
