Verified Answer :

split it up, aka make a net diagarm or something whatever its called

we have
2 triangles (top and bottom)
2 side rectangles (visible ons on side)
back rectangle

area of triangle=1/2bh
b=6
h=4
1/264=12
times 2 since 2 trigangles
212=24

2 side rectangles
LW=A
5
10=50
times 2 since 2 of them
502=100

back rectangle
6 by 10
6
10=60

add everybody
24+100+60=184 cm^2
