Answer:
320
Step-by-step explanation:
To find the surface area of the figure, add up all of the areas of the faces. The surface area of the rectangular prism on the left is 3(10 x 4) + 2(4 x 4) + (6 x 4) and the one on the right is 4(8 x 4) + (4 x 4). The surface area of the entire figure is 320 cm2.
