Answer:

0.64m squared

Step-by-step explanation:

Surface area is the area of the sides added together

I am going to assume that the bottom is a square

0.4 multiplied by 0.6 is 0.24

0.24 halved is 0.12

0.12 multiplied by 4 is 0.48

0.4 multiplied by 0.4 is 0.16

0.48 plus 0.16 is 0.64

Answer:

0.64 m²

Step-by-step explanation:

Total Surface Area : Area (4 triangles) + Area (square)

  • 4 x 1/2 x 0.4 x 0.6 + (0.4)²
  • 2 x 0.24 + 0.16
  • 0.48 + 0.16
  • 0.64 m²
