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.
