Question

6 ft 10 ft 8 ft what is the surface area of this rectangular prism? sa = ft²

Explanation:

Step1: Recall the surface area formula

The formula for the surface area of a rectangular prism is \(SA = 2(lw+lh + wh)\), where \(l\) is length, \(w\) is width, and \(h\) is height. Here, \(l = 10\) ft, \(w=8\) ft, \(h = 6\) ft.

Step2: Calculate each product

• Calculate \(lw\): \(lw=10\times8 = 80\)
• Calculate \(lh\): \(lh=10\times6=60\)
• Calculate \(wh\): \(wh=8\times6 = 48\)

Step3: Sum the products and multiply by 2

First, sum the products: \(80 + 60+48=188\). Then multiply by 2: \(SA=2\times188\)

Answer:

\(376\)
