Answer:


A = 66\ yd^2

Explanation:

You can either add up all the areas of the faces of the rectangular prism, or you can use the following formula:


A = 2(wl+hl+hw)\\A = 2(3 * 3 + 4 * 3 + 4 * 3)\\A = 2(9+12+12)\\A = 2(33)\\A = 66

Answer:

The surface area of the rectangular prism is
66\ yd^2

Explanation:

Step 1: Find the area of the front and back


A = l * w


A = 3\ yd * 4\ yd


A = 12\ yd^2 * 2


A = 24\ yd^2

Step 2: Find the area of the top and bottom


A = l * w


A = 3\ yd * 3\ yd


A = 9\ yd^2 * 2


A = 18\ yd^2

Step 3: Find the area of the left and right sides


A = l * w


A = 3\ yd * 4\ yd


A = 12\ yd^2 * 2


A = 24\ yd^2

Step 4: Total area


A_(total) = 24\ yd^2 + 18\ yd^2 + 24\ yd^2


A_(total)= 66\ yd^2

Answer: The surface area of the rectangular prism is
66\ yd^2
