94m² is the answer
the surface area of 3m, 5m, 4m
This means it's a rectangular prism with a length, width, height
the rectangular prism has 2 sides each ( meaning for the area of one side, you multiply by 2
3 x 5 = 15 x 2 = 30m²
3 x 4 = 12 x 2 = 24m²
4 x 5 = 20 x 2 = 40m²
surface area = 30 + 24 + 40 = 94m²
