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
