Question

12 ft. 6 ft. 11 ft. which diagram is a net for this prism? 12 ft. 11 ft. 6 ft. 12 ft. 11 ft. 6 ft. 6 ft. 11 ft. 12 ft. 11 ft. 6 ft. 12 ft. 6 ft. 6 ft. 11 ft. 12 ft. what is the surface area of the rectangular prism? square feet

Explanation:

Step1: Recall the formula for the surface area of a rectangular prism

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

Step2: Identify the values of \( l \), \( w \), and \( h \)

From the prism, we have \( l = 11 \) ft, \( w = 6 \) ft, and \( h = 12 \) ft.

Step3: Calculate each term inside the parentheses

• Calculate \( lw \): \( 11\times6 = 66 \)
• Calculate \( lh \): \( 11\times12 = 132 \)
• Calculate \( wh \): \( 6\times12 = 72 \)

Step4: Sum the terms and multiply by 2

First, sum the terms: \( 66 + 132 + 72 = 270 \)
Then, multiply by 2: \( 2\times270 = 540 \)

Answer:

540
