SA = 18.2+10.4h

59.8yd²

Step-by-step explanation:

Surface area of a 3D shape is the sum of the areas of its faces. A rectangular prism is made of 2 rectangles that make the top and bottom, plus four equal, larger rectangles.

surface area = 2(small rectangles)+4(large rectangles)

surface area = 2(3.5*2.6)+4(2.6h)

SA = 18.2+10.4h

SA = 18.2+10.4h

SA = 18.2+10.4(4)

SA = 18.2+41.6

SA = 59.8yd²
