Which equation can be used to calculate the surface area of the triangular prism net show below?

Mathematics
1 answer:
erastovalidia [21]4 years ago
4 0

Answer:

360cm

Step-by-step explanation:

The top square is 10 x 13 = 130

The middle square is 10 x 12 = 120

Both side triangles are 5 x 12 = 60. You would halve it but there are two triangles.

5 x 10 = 50

50 + 120 = 170

170 + 130 = 300

300 + 60 = 360

Equation would be (10 x 13) + (10 x 12) + (5 x 12/2) + (5 x 12/2) + (10 x 5)

The equation options seem like they are missing some numbers or something
