Question

This one is really confusing me

What is the surface area of the figure?



310 cm2

360 cm2

155 cm2

180 cm2

Answer 1

Answer: 155cm

Step-by-step explanation: Multiply all of the sides together or add if you add it would give you the answer of 39 but I think you’d go better along with multiplying.

Answer 2

Answer:155

Explanation

Divide it into symmetries

Symmetry 1,=10×5=50

Second symmetry =5×4=20

Third =5×4=20

Forth =5×4=20

Firth =5×4=20

Sixth =5×5=25

Total =50+20+20+20+20+25=155
