5 m
7 m
4 m
140 m squared
16 m squared
166 m squared
156 m squared

Answer 1

166 m²

Explanation:

Surface Area

• 2(length x breadth) + 2(length x height) + 2(breadth x height)
• 2(7 x 4) + 2(7 x 5) + 2(4 x 5)
• 2(28) + 2(35) + 2(20)
• 56 + 70 + 40
• 110 + 56
• 166 m²

Answer 2

140 m squared is the surface area.
