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
1/2*6*4=12
times 2 since 2 trigangles
2*12=24
2 side rectangles
LW=A
5*10=50
times 2 since 2 of them
50*2=100
back rectangle
6 by 10
6*10=60
add everybody
24+100+60=184 cm^2
