Question

find the surface area of the figure
a 600 ft²
b 60 ft²
c 300 ft²
d 240 ft²

Explanation:

Step1: Recall the formula for the surface area of a cube

The surface area formula for a cube is \(SA = 6s^{2}\), where \(s\) is the side - length of the cube.

Step2: Substitute the value of \(s\) into the formula

Given \(s = 10\) ft. Then \(SA=6\times(10)^{2}\).
First, calculate \((10)^{2}=100\).
Then, \(6\times100 = 600\) \(ft^{2}\).

Answer:

A. \(600\ ft^{2}\)
