Question

What is the total surface area of the figure below? Only enter the number part of your answer. Do not include the units.

Answer 1

193.2

Explanation:

To solve the triangle:

5.2 × 6= 31.2

You would normally find half of that since it's a triangle but there are two triangles, so each would equal half of 31.2 but if you add both halves that just equals 31.2.

Square one:

9 × 6= 54

All three squares are equal since they have the same measurements.

54 + 54 + 54= 162

162 + 31.2= 193.2
