Answer:

622m²

Explanation:

a right rectangular prism will have 6 sides and the parallel sides of the prism will be the same size

so we work out the given surface areas and multiply each by 2

7 x 11 = 77

times 2 is 154

11 x 13 = 143

times 2 is 286

7 x 13 = 91

times 2 is 182

then we add it all up

154 + 286 + 182 = 622m²
