Answer:

94 square ft

Explanation:

as given in the question, the formula for surface area is 2lw + 2lh + 2wh, which means (2 × length × width) + (2 × length × height) + (2 × width × height). since these values are given, we just have to place them into the equation as such:

(2 × 5 × 4) + (2 × 5 × 3) + (2 × 4 × 3)

= 40 + 30 + 24

= <u>94</u>

so, the surface area is 94 square ft.
