Question

find the lateral area of the cube. 9 in. 9 in. 9 in. square inches

Explanation:

Step1: Recall lateral area formula for cube

A cube has 4 lateral faces (excluding top and bottom). Each face is a square with side length \( s \). The area of one square face is \( s^2 \), so lateral area \( LA = 4s^2 \).

Step2: Substitute side length \( s = 9 \) in

Given \( s = 9 \) inches, substitute into the formula: \( LA = 4\times(9)^2 \).

Step3: Calculate \( 9^2 \) and then multiply by 4

First, \( 9^2 = 81 \). Then, \( 4\times81 = 324 \).

Answer:

324
