Answer 1

surface area =0.1357

Explanation:

first, find the triangle area

to find use triangle area= base x height divided by 2

so .18 x .23

=0.0414

divided by 2

= .0207

multiplty 0.0414 by 4 because theres a total of 4 triangle sides

.0207 x 4 = 0.0828

now find the area of the square on the bottom

area= base x height

.23 x .23 = 0.0529

now add the two areas together

0.0529 + 0.0828= 0.1357
