Question

find the lateral area of the cube.
10 yd.
10 yd. 10 yd.
square yards

Explanation:

Step1: Recall the formula for lateral area of a cube

The lateral area of a cube is given by the formula \( LA = 4s^2 \), where \( s \) is the length of the side of the cube.

Step2: Identify the side length of the cube

From the diagram, the side length \( s \) of the cube is 10 yards.

Step3: Substitute the value of \( s \) into the formula

Substitute \( s = 10 \) into \( LA = 4s^2 \). So we have \( LA = 4\times(10)^2 \).
First, calculate \( (10)^2 = 100 \). Then, multiply by 4: \( 4\times100 = 400 \).

Answer:

400
